needed another.. 1 is not enough!
|
Time owned: more than 12 months
|
Ordered another as the one in the air is staying! I have a beam and all that but the EF40/20/10 is a great go to antenna.
It's robust, with I have Qrp radios I've used it on 40M running my HW101 and more than a few times forgot the back off the drive without damage.
The one in the air has done a few winters and no problems with ice pulling it down or being unusable with ice on it. The wire has not sagged
or stretched.
I string mine between a 32ft stacking aluminum military mast and a 22ft crappy pole for field work. Makes a good confined spaces antenna for 40M as it's 40ft length is easier to work with than a full size 40M (66ft).
It's a good portable antenna. Which is why I now have two of the EF40/20/10s and a EF40 and EF6 for utility work. The end feed makes the setup much easier. Get it in the air and 3 bands no sweat, no tuner. If I need an odd band outside 40/20/10 a spare wire trimmed to anything from 5 to 30mhz is easy to do.
Give it 5 all the way especially for customer service. I've recommended it and the monobanders
as easy to erect, easy to tune, and just works.

Spoke with Dale on the phone about this antenna and he built one for me even though he was extremely busy with filter orders! His customer service is first class and he will answer E-mails within 1-2 hours, not bad for a busy guy!! I received the antenna via UPS today and had it tuned in about 10 minutes, shortly after tuning I worked the U.K. on 40! Funny thing is I still had my radio turned down to 5 watts for tuning, received a 5/5 report. It works great. Get one and have fun. Mike KC2PLJ

I cannot imagine a better QRP/low power antenna for use with my Yaesu 817ND and ICOM 718 (at low power). On 40M, send and receive reports are only about one S unit less than my full size dipole. I can work east and west coasts from my Oklahoma QTH with regularity. Quality of the antenna is excellent. Dale Parfit is a delight to work with. I also have an MP-1 but never use it because the End Fedz is so easy!

Living in an apartment has many drawbacks for ham radio. Having to do it in a bad location for ham radio makes it worse. Little room for an outdoor antenna, second floor apartment, almost fully surrounded by buildings, and well below the surrounding terrain. Not to mention power line proximity and noise and nosy neighbors. I have used just about every commercial antenna available and every home brew antenna imaginable. Buddipole, MP-1, Hustler verticals, G5rv Jr, Isotrons, trap dipoles, Fishing pole antenna's, loops of every geometric shape. They have all worked to some extent and many have worked quite well even with the constraints I have. Some did not work at all. Some were ugly. Some were too much of a pain to set up and take down. . The EF-10/20/40 has by far performed more consistently than any other antenna I have used at this QTH. I still have to work harder and longer than most others to make contacts. But I have more qso's more often. In the last week I have worked my firsts in Alaska, Denmark, and Iceland. Not much for most people but a small slice of ham heaven for me. The bottom of the sunspot cycle. 25 watts. And I am having fun. How do you put a price on that? I can take the antenna down in 10 minutes if I want to take it camping with me. Put this together with ease of setup, low visibility, and Dale's great customer service and you have a first rate antenna from a first rate company.

Outstanding Antenna/Outstanding Value
|
Time owned: 3 to 6 months

PAR Electronics Antennas are terrific - you can gather that by all the 5 star reviews. However, let me add my own experiences and views.
First - I build most of my antennas; total count about 10, purchased 3. Dale's antennas (PAR electronics) are worth every penny.
Quality of product: 10 - this thing is ROBUST - It is rated for 25 watts I have pushed 20 through it quite a bit - no problems. I suspect in an emergency it could go higher - wouldn't hesitate if situation called for it.
Ease of set up: 10+ It comes with directions that are easy to follow and WORK! Please take the time to tune this antenna up when you first use it; it is close as it comes out of the box, but it deserves your efforts. As delivered mine was right where the instructions indicated, just below 20 meters; a couple of snips and I'm set for 14.070 with SWR of 1:1.1 and 2:1 at the top of 20m. It takes maybe 30 minutes if you are cautious, careful and anal-retentive (is that hyphenated - I always worry). When Dale says an inch trimmed of raises it 35kHz - it does. I use an analyzer to tune this but a SWR meter would work great.
Performance: 10+++ This thing works. I have used it on the beach operating /4 and regularly QSOd with Europe and South America with 20 watts from an SGC2020 on SSB and PSK31. It puts the power into the aether! Hang it off the balconey or . . .my favorite . . . take it down to the beach, string it up to a 31 foot Jakeite pole and run as a sloper. Don't forget the beach chair and the adult beverages. Perfect way to wind down after a day of meetings (what - you don't think I was at the beach for fun!). Seriously - gives a great low angle of radiation and at dusk really catches the grayline.
Support/Customer Interaction: None better anywhere. 10^2. Dale is an active ham, he is proud of his products and he wants yours to work. Problems or issues -- email or call and you WILL get support right NOW.
Overall - Easy to pack, should last for decades. This is the one I always pack!!!!!

Tim, K3DET, could find no other way to contact you so just wanted you to know that morse code is no longer a requirement for hams in the US. So go buy a General License study guide and get busy. No excuses any more!

And yes, as for the Par End-Fedz....I'm in the process of purchasing a few and will report back.

Let me preface this review by saying I am not one to go out and buy my antennas for the most part. This little gem was an exception and worth every penny spent.
FYBO (A QRP Field event) was comming up and I wanted something better that what I had been using that was easy to set up, multi-banded for the most active bands in the contest, inexpensive (aren't all hams cheap?) and convienant to use. I had been using dipoles at low heights, other adapted trap verticals and a full size 20 meter ground plane in the past with mixed results.
Arriving at the site to on the air was a total of 40 minutes and I move SLOW. 31' JackKite pole with a 16' Harbor Freight flag pole stuck up the bottom was the support and it was bungeed to a large C-Clamp attached to the roof of the ramada and a trash can for the base support. Small bungee ball wraps were used at the load coil about 6'from the tip to hold it to the mast and the rest of the antenna was just sloped away about 15' from the mast at the feed point. Atttach coax, hook up Icom 703 and I am on the air.
SWR? What SWR? When I pretuned this antenna at home the final SWR was almost unmeasurable on 20, below 1.4 to 1 on 40 and 10. Heck, even 17M wasn't unusable.
Conditions were not what that hot. I worked everything I could hear including 3 stations in Canada and a VK4 during the event and all with 5 watts.
Am I a happy customer? Yep.
OH! BTW, If you invest in one of these little bueaties, DON"T USE an MFJ 259 or 269 to set it up. The device will just be confused and NOT give you accurate indications at all. Just set it up with an SWR meter and a chunk of coax and be done with it. It drove me nuts for 4 days trying to figure out what was wrong when the best SWR I could see was above 4:1 with Ø ohms resistive and 45 ohms reactive!
A phone call to Dale yielded a replacement matching unit and a new 20 meter wire just in case but they indicated the same thing. When I did it the old fashion was, all was right with the world.
I kept the other parts and sold them to a fellow ScQRPion who already had two of his antennas and wanted one of his own for travel!
This fellow goes out of his way to make the customer happy. He build a quality product that does exactly what he says it will and is approachable, knowledgable and friendly. (Gee, sound like an old school Ham to me!) In short, take the time to check out PAR Electronics web site and then, as they say in the NIKE commercial, "JUST DO IT" and get on the air!
I have no financial interst in PAR Electronics other than a happy customer.
Keep up the good work Dale.

A 35 foot Dream come True
|
Time owned: 6 to 12 months

Hello Everyone,
Before I go on telling you about the PAR antenna please let me tell you about my situation here where I live.
Being disabled I had to move into a HUD building.
I picked the 4th floor dreaming of a nice sized craw space.
My dreams were shattered when I moved in.
There isn't any craw space.
The place was built to take a bomb blast (REALLY)
My entrance door is steel have 6" of concrete and 1/4" corrugated steel above and below me.
Enough steel here to build a bridge to NY City.
I tried all types of wire antennas and I settled on the MAG LOOP that seemed to work fine but I did miss the ability to move around the band and not have to retune every few KC.
I had the PAR antenna 10/20/40 meter version.
One night I decided to toss the antenna out of the 4th floor window and I was impressed that any noise coming from the building was just as low or lower then the MAG LOOP
It's slopped appx 45* down and the working end is about 20 feet off the ground.
I'm far from an EE and just know a fair amount of information on antennas.
The MAG LOOP did get me some good DX but it doesn't hear that well inside this steel box.
I used my home made end fed when parked and tossed the 65 foot wire into the trees.
However 65 foot of wire it a lot of tossing and hard to get vertical.
The PAR 40/20 and 10 meter is perfect for stationary mobile and at around 35 feet works as well as the 65 foot wire.
It's short enough to drop out of the window then reel it in when I'm finished using it.
I took my time and tuned the PAR on 20 meters and then on 40 meters.
It seems no matter where I deploy the PAR antenna so far I never saw an SWR higher then 1.5-1 and almost all the time it around 1.3-to 1
I then remember reading about tuning the PAR for 40 meters up at the far end.
I got the SWR FLAT!-ZERO.
My first try from this building I dropped the wire out and secured it with a 15 foot long piece of mono line and thumb tacked it to what was left of a tree stump,APPX. 3 feet high and left the PAR Antenna working end of the antenna about 5 feet off the ground.
I came back up on the 4th floor and was impressed and very happy that I was again able to tune around and not worry about retuning every 5 KC.
I had my FT-817 @ 5 watts, on the 13.8 Power supply and my very 1st QSO was with France.
Not that far but very good considering less then 300 feet from me is the back wall of a shopping mall and the antenna sloping down and facing Southeast.
After a few QSO's and about 6 weeks later I decided to look for another spot where I can get the working end higher.
I found the remains of a tree that was torn out from a tornado.
I tossed some mono line over that and was happy to see the working end now APPX 20 feet off the ground.
I came back up and I worked a ham down in FL.
I also worked the Virgin Islands and I bagged 1 QSO from Poland and another one in Italy.
For the 1st time in 2 years that I heard about it,
I was able to receive the Russian single letter Beacon.
On FEB.12,2009,on 20 meters I worked to hams in Germany.
I was not able to hear them on the MAG LOOP and my reports weren't that great on the PAR but calls and RST were exchanged.
Between operating from this 4th floor bunker and my three outdoor locations I have had no need to ever, even think of retuning the par and at 35 feet long it does as well as the 65 foot wire and I do have several QRPp QSL cards here from my Rock-Mite beacon.
My motto is DX may be far but you can work them with a PAR.

I forgot to mention that if you *ARE NOT* antenna restricted the PAR antenna is the way to go.
You can crank it down with a turn buckle and make it as tight as a guitar string and it won't break.
100% QUALITY PARTS!
You can also run the wire in almost any configuration and if the SWR isn't below 1.5 then just do the tuning steps. If your thinking that the 65 foot wire is better, try finding a tree that high in your back yard.
Almost all 65 foot wires are not vertical but the PAR at 35 feet long can be strung up close to vertical with no problem and works as well as the 65 foot wire that is almost always sloping upward not much more then 30-to 40 feet.
In my previous post I forgot to mention that last month I laid the PAR wire on the floor in the hall way at 2 AM just to see what it would do.
Below is part of the E mail I received.
----------------------------
Hello my freind Bob
Thank you for e-mail and QSO , ur signal very strong 599 in Santiago de Cuba
Not bad for 5 watts and a wire laying on a concrete floor with 1/4" steel supporting all the weight.

Again, Dale is customer friendly to the max. He was busy with Gov. orders, but since we had chatted about the antenna previously he graciously found time to produce one. Up in a tree, sloped to the roof of my SUV in the parking lot of my condo. Bit of tweaking on 40 and 20 and it WORKS!!! 2.5 watts with my FT817. I can find no fault with this antenna, it does what is designed for. The quality is outstanding. Great product, great guy to deal with, great value! What more could you ask for.
