HF End Fed Antenna, 4 Band 8 Band 1MHz to 30MHz 100W Power End Fed Radio Antenna SSB FT8, FM, FSK for Outdoor

Put it in use today. Used it as an inverted V, 40m half wave, 20 ga wire, ends suspended just 3 foot off ground, 21 foot center mast.It's performing very well, and was also able to also tune 15 and 6m, with the ic7300 internal tuner (swr was about 2.5 on these).So easy to deploy the efhw, and works so well with this 64 unun. I used online calculator and have approx 63 or 64 feet in the V for length, and honestly, I haven't done much in the way of tuning it, as it's 1.1 on 10 and 20m, with 1.5 on 40m.I've already made solid contacts on these bands, and I am very, very satisfied.

decided that inverted v antennas were too much work trying to deploy multiple was a nightmere. had this thing going in less than half an hour. I get 20/12/10 and 6. Didnt have enough wire to make it for 40. 12m doesnt need tuning at all. the other 3 tune with the internal tuner on the 991A. I will be adding 25 more feet of wire tomorrow to try out 40m! well constructed and very good recieve.

I get about 1-1.5 higher s meter recieve than my (30ft straight parallel to ground) dipole, and great swr at 10, 20 and 40m. I could probably adjust for 80 but I don't use the band currently.If you're new to endfed this was very easy to get some prototype ideas and testing for antenna line, something in it does rattle a bit but it does function on recieve. I'll try to get back with Tx quality.

Nice UNUN, but it's missing a ground post for attaching a counterpoise. I was able to open the unit and add one and solder it to the shield of the UHF connector. I sealed it back up with some non-conductive sealant. By the way, the toroid and windings inside look to be high-quality.

Been using for a couple of weeks now. So far, so good!

I tuned mine for the bottom of the 80m band which gives me 1.5 or below swr on 80m, 40m, 20m, 15m, 12m and 10m. It also tunes very easily on 30m, 17m and even 6m with the internal tuner in my IC-7300. I did have some issues with RF getting in my shack but was remedied with a MFJ-915 and also burying my coax to the feed point about 60 feet from the shack. I put it up as an inverted vee with the feed point about 5ft off the ground and the apex up around 35 feet somewhere near the center of the 14ga thhn wire and the other end anchored to a fence post with about 10 feet of good nylon cord. I did not use a counterpoise in this installation and have had absolutely no problems breaking pileups. I put it up with it facing east to west and it has served me well being in Mississippi. Seems to be fairly omni directional as I have worked as many stations due north and south as I have east and west. I use it for ssb as well as digital modes.

Works well for EFHW. This unun does not have an external connection for a counterpoise but I was able to easily add one.

Solid construction and I liked the case design that makes it easy to hang on hook or other support. The price is right too !Image from AntScope and is preliminary trimming and location is close to pontoon boat and truck. Sloped from 25’ to 7’. Going to relocate into the open and proceed with trimming.
