DX monster
|
Time owned: more than 12 months
|
I operated as ZF2TE for a week on Grand Cayman with the LNR half waves- only 60 watts output, but generally got 5-9 signal reports from Europe, Asia Africa and Natam.
I used the 2.2 pound DK9SQ Kanga pole to support the radiators ocean side and just taped the EndFedz to the pole. The Kanga pole telescopes from 46 inches to 33 feet. Handy for backpacking too.
If you have not used a 1/2 wave vertical next to the ocean, you should give it a try.
I have also used these antennas well inland with great effect.
Well built, easy to pack, awesome performance.

EF-40/20 the only antenna you need

The end fed design is ideal for my small city QTH, easy to install with clear instructions, simple to tune. Works so well that what I thought would be a short-term solution became my permanent 40m antenna. Very well constructed, I expect it to last a long time.

6 m antenna
|
Time owned: more than 12 months
|
|
I bought a PAR 6 m antenna before LNR bought the former company. It works very well, I would NOT pay the price of the new antennas as they can be easily made for about half or less money. I dont know how they can justify doubling the price immediately after purchasing. A piece of wire and a torroid. Thats it.

EF-40/20 - It just works!
|
Time owned: 0 to 3 months

Bought the EF-40/20. There are no tall trees here so I have mine mounted as a sloper off a 20 ft PVC mast with 75 ft of DXE-400MAX coax connected to matchbox 5 ft off the ground. Not exactly the optimum position but thought I'd give it a try. Tuning took a bit longer than it should have because instead of come from the factory 66' 6" long it was 68 ft and I didn't measure it first. Tuning is easy though and set 40m low SWR for phone but wrapped some of the wire back on to itself instead of cutting it all off so I can retune for CW later. Connected it to my IC-756Pro II and was amazed with QSO's in Europe, Cuba, deep South America and all over North America. Wish it had 10m too but wanted 100 watt version. Going to try it on a taller mast soon but it works well where it's at. It doesn't get any easier than this!

I have the LNR Precision model EF 20/40 and I must say that I am very impressed with this antenna.The production quality is top notch and the antenna is easy to deploy.The instructions are well written and tuning was a snap.Now I can work qrp without a tuner.On my first trip out I made several contacts on both bands running 4 watts with my Ten Tec qrp rig.This is a great simple antenna.

Great Antenna, 1.02 SWR, brilliant reception
|
Time owned: 0 to 3 months
|
Bought the 10M and 20M End-Fed wires for my FT-857D a few weeks ago. Tried the 10M with my new FT-857D today. The 10M wire was hanged at the congested backyard of my house (8 feet from my house and about 15 feet away from my neighbour). It was lifted about 16 feet from the ground, the end match box was hanging diagonally 1.2 meters above ground. The highest point was about the same level of the roof my house and that of my neighbour. As such, I thought that it would not be an ideal place for the wire.
Out of my expectation, I got on to a few hams this afternoon and got 5.9 signal reports from them. One of the ham's signal was so strong as if he was banging on my door.
Brilliant wire antenna design and quality. thumbs up.
Will try the 20M wire later and will relocate the 10M wire see if I can get even better reception. Will write again once done.

a must for a HF go kit!

I was in Coleman, OK (EM14si) and strung it up between two trees and started working all over the americas and the western pacific that night. for sure I was making it into Japan, New Caledonia, and the Kamkatcha Penninsula. NO TUNER REQUIRED! I say that this was the best $60 I have ever spent on a wire antenna. I plan on buying more in the future and may even use it at field day!

Still Impressed

Well Saturday came and i got to test the End Fed on 20m. I hung it up 8m off the ground again and got a good report into vk2 on ssb then just near our sunset i worked OK1 on 20m cw but i was running the ic 703 at 10 watts .But thats a long way away from downunder.
73 to all hope to make stateside soon de Ian vk5cz..

I had my antenna 1 hour out the box and up a tree . Made a couple snips to the 40m radiator and got good swr at bottom of 40m and 45 ohms at 1.2.1 on 20m stub. Worked vk4drx on 40m cw with my old ic 703 at 5 watts about 1400 km away rst 578. First ssb qso still on 5 watt setting about 200 km to vk5hs rs 5/7 . No qso on 20m run out of time. Antenna was horizontal between two trees 8m high with 10m of rg8 coax droping straight to ground from the magic box. iam impressed de vk5cz ian in clare sa.

Works Well So Far
|
Time owned: 0 to 3 months

I promised myself that I wouldn't get online and praise its merits before a solid series of tests. But, so far, I have been impressed. So. I figured I would post from my blog:
20 Meter EndFedz Works Great
I did some more experimenting with my EndFedz. I finally got the standoff at the top of my tower, so I fastened it to the rope and pulled it up to the pulley. At about 32 feet high and sloping to about 15 feet, I made some successful QSOs from Mexico City to California, to Maine and to Europe. I checked in on the Maritime, SATERN and Intercon nets.
Regarding SWR, I haven't used an analyzer yet, but I measured it, used it with a tuner for a while just in case the SWR was a bit high (no, a tuner won't hurt it; you don't need one). After a while, I shortened it by an inch or so, and my FT-450 meter only shows one bar when I key and talk.
To test it further, I started at the top of the band, and went all the way through the data section with the tuner. It tuned it without any problems, so I know it was under a 3:1 SWR. With a stated SWR of 1.5:1 for 300 kHz, that goes to within 50 kHz of the bottom of the 20 meter band. It seems logical that it will perform sufficiently to the bottom edge, given that small amount of difference.
At QRP, the Maritime Net gave me a a copy, but the band static and other stations made it difficult to copy all of my call sign. Cranking it up to 100 watts solved that problem.
I plan on trying it out in the different configurations, such as an L, horizontal, and vertical as soon as I can. I suspect using it as an L would give it more of a directional approach, but don't quote me on that... I'd also like to see how much adjusting the takeoff angle actually affects it, as well as height above ground. The direction it is pointed as a sloper does seem to affect the direction somewhat.
