Reviews Summary for Alpha Antenna 6-160 HF J-Pole
Alpha Antenna 6-160 HF J-Pole Reviews: 38 Average rating: 4.7/5 MSRP: $119
Description: Get on 6 through 160 meters with Alpha J-Pole Sr or Jr Antenna. The unique design characteristics of the Alpha JPole Antenna enables the Jr version to achieve resonance on the major HF bands (6/10/15/20/40 Meters) and presents a SWR on 80 & 160 Meters that is low enough for your antenna tuner to achieve a perfect match. Likewise, the Sr version presents resonance that is also low enough for your antenna tuner to achieve a perfect match on all HF bands.

A combination of antenna designs, namely the JPole and Zepp along with matching network technologies, were used to design a J-Pole antenna systems for 6 though 160 meters. We derive the J‐Pole wire lengths, spacing of the wiring in their respective sheaths, size & number of the strands of the wire from a combination of J-Pole and Zepp antenna formulas. From the Zepp is the feeder type design, and although significant, is by no means the only factor in matching the antenna. The matching networks then allows for the antenna to be fed with 50 ohm coax at the antenna. This makes for an important design characteristic when feeding a tuner, as it keeps the RF voltages low at the base feed point. Your tuner then performs the final matching for resonance.

Technical Specifications - Weight: 1.5 pounds - Configuration: Vertical (for more DX), Horizontal (for more NVIS), or Sloper (for DX and NVIS) - Frequency Coverage: 1.8 to 54 MHz - Power Rating: 750 watts PEP Sr and 200 watts PEP Jr

better than advertised   Time owned: 6 to 12 months
I bought the Alpha Antenna J-Pole Sr back in April of this year, I used it for about 2 weeks with good results and then something went out of whack.. The swr was going all over the place on all bands. I put my 20 meter end fed back up on the same feed line and that seemed to worked OK. I called Alpha Antenna and explained to Steve what was happening. After a few questions Steve was more than willing to have me send it back for repair. The next day I was having the same problem with the 20 meter end fed.. Needless to say the problem was my feed line..
I now have both the Jr and Sr version of the Alpha Antenna J-Pole. It's amazing how well these antennas work..

Great antenna's with with excellent customer service..

amazing antenna. first dx contact ever after 20 minutes of use  Time owned: 0 to 3 months
I live in a hoa and am unable to put a tower or a large permanent antenna. I put the alpha antenna up on fiberglass poles at 20 ft and ran it as a sloper to a tree. Had it up for about 20 minutes and made a local contact on 15m. Then a friend informed me of a Japan contest and tuned to 21.317. Made a call to ja5fdj and he replied right back. Confirmed callsigns twice and exchanged signal reports. I was so happy. This was my first dx contact ever and it was so easy. 6170 miles from a 35 ft wire antenna that I put up in 3 minutes. I could hear stations in the Caribbean islands and south America very well on 10m this morning. I'm excited to use this antenna and make some contacts! Thank you Alpha Antenna!!

Awesome Antenna  Time owned: 0 to 3 months
Put this up as a sloper,and worked DX on PSK with 35 watts.No problems what so ever.Highly recommended when space is limited.

An effective antenna  Time owned: 0 to 3 months
I was amazed at how flat this antenna tunes across the bands.
Have worked plenty of DX.
Great customer support. To do over, I would buy this antenna again and would replace it if need be.

Better than it should be!  Time owned: 0 to 3 months
I chose this antenna as a hidden solution for my yard. I needed a full-spectrum solution that I could install higher than the working ATAS-120A I have on a 5' mast with counterpoise.

I was able to toss a rock taped with para-cord up approx 30'. After attaching my coax run to Alpha Antenna's "balun," I pulled coax and feed-point into the tree. The distal end is tied to a flexible bush 5' off the ground.

I was very surprised that my internal tuner in the FT-450D tuned each band 120-10. That wasn't 'supposed' to happen. I believe what makes this work is having the feed point as high as possible with the ceramic distal end tied low. (Or horizontal if that works for your location.)

My first contact was Sergey, UA0FO in Asiatic Russia. I'm sitting in SW Idaho using 100 Wts. In the first hour after I pulled this antenna up I've received nothing lower than 5/9 as a signal response.

There are bigger, 'better' antennas out there for certain. However, for my needs -- a full spectrum antenna that my rig can tune allowing for clear send/rcv -- This solution does it all. I fully recommend this affordable antenna for its functionality and in how it's backed by great customer support.

Thanks Alpha!

Works well.  Time owned: 0 to 3 months
I recently moved to a deed-restricted community in Florida and had not a clue about how I was going to get back on the air again. I heard about the Sr model which was only 35 feet long and I thought that at least I could string that up in my attic. My expectations were not high, but after being on the air foe two days, I worked Austria this morning on 10 meters using an Icom 7200 and 100 watts. I am pleased.

Alpha 6-160 SR Antenna  Time owned: 3 to 6 months
I received one of the first Alpha 6-160 SR antenna's and thought there was NO way this antenna would work or radiate a signal at only 34 length of wire. I was impressed with the matching unit which was much bigger than the one with my Alpha 6-160 Jr antenna. I installed the antenna and much to my SURPRISE my internal tuner on my FT-950 tuned this antenna on ALL bands 160 - 6 meters. It is one thing to tune it is another thing to communicate. On 75 meters I was able to test my vertical, my Alpha 6-160 Jr., and the Alpha 6-160 SR antenna. Hands down I received the BEST signal report on the Alpha 6-160 SR antenna. I was truly AMAZED ! I would recommend this antenna especially to someone that is space challenged.

Jr and Sr both awesome  Time owned: 6 to 12 months
I originally purchased a Jr. About a year ago. Steve at Alpha was able to give me some great ideas on where to install as a roof top antenna. Out of the box, it was a quick and easy installation. The SWR on all bands makes it tunable on all frequencies. I was locked on to Hawaii SSB with 100 watts right away 59's. So pleased with the Jr, I purchased a Sr, about six months ago. The Sr went up with the same if not better results. The Jr. Comes with a storage frame and is now my portable antenna. The Sr now has me talking to Japan, and the east coast from California. It has a permanent place on my roof.
The jr is only rated for 200 watts, but the sr is rated for 750 watts. The Sr is a bit noisier, but not out of line as it is quieter than my G5RV . The sr also gets better reception than the G5RV.
This antenna has not been approved by the XYL, but she doesn't even know it exists. Stealth

This antenna continues to amaze me  Time owned: 3 to 6 months
Follow-up review
This review is a follow-up to my original review posted in August 2013. It is for the Junior (Jr). I have no experience with the Senior (Sr) version.

My original rating still stands. It continues to perform and it amazes me with the results I obtain.

I am located in a local valley, surrounded by mountains. Ground conditions are dry and rocky. I run about 40' of LMR400 to get to the antenna. It is set-up as a permanent installation. It runs from a tree as an Inverted L in a N/S orientation. The only addition I have made is a ground system running from the LMR400/antenna PL-259 connection to a 8' grounding rod, located at the base of the tree. Besides providing some lightening protection, some day I plan to experiment with radials attached to the grounding rod.

I use a MFJ-969 tuner. Most of my experience has been with 75, 40, & 20 meters. On 40 & 20 I can obtain a 1:1 SWR. The best I can obtain on 80m is a 2.5:1 SWR. 2:1 is a loss of about 1/2 db so I find that acceptable. Since the SWR can be affected by a number of factors, your mileage may vary.

The last couple of months, I have been on the 75, 40, 20, and 15m bands running 100w on the OMISS Net ( OMISS is a primarily a WAS and awards net. A great group of people by the way.

After a few evenings, I am only 8 states away from my 40m OMISS WAS award. From my "Big Sky" state of Montana, I have worked Hawaii, Alaska to Florida, California to New Hampshire, and Canada to Texas. My personal favorite was WL7X in North Pole, Alaska.

The downside to this antenna is that there is no local bragging rights. There is no tower or revolving Yagi. No magic Christmas tree looking affair. It's a simple black wire running from a tree, to the railing on my deck. My neighbors haven't notice it and if I point it out, the response is, "Oh". It certainly isn't impressive looking. The other downside is that it doesn't operate very well as a NVIS (at least how I have it configured) and now the wife doesn't understand why I need another antenna.

For what some would call a "compromise" antenna, I couldn't be happier. It's producing results.

*** August 2013 Review ***
My Alpha J-Pole Jr is set up on a permanent basis as an Inverted L. It hangs from a tree, about 20 feet above the ground. From Montana, I was able to bust a pileup with Croatia using 100w. It's a keeper.
