I had it shipped to Wales, UK where I was on vacation. I bought this EFHW 80-10 antenna in early September 2015.

It works well, it’s multi-band, it complements my other antennas and is relatively easy to install being an end-fed. So I can say the EFHW-8010 works very well.Īll in all, I’m very satisfied with the antenna. On some occasions the EFHW-8010 is a little better, and sometimes it’s not – but it’s close. I’ve done comparisons to my 40m and 80m dipoles as well as my 6BTV multiband vertical and the performance is very similar. The antenna doesn’t do quite as well on 17m and 30m (the harmonic relationship of these bands is a bit off) and SWR is 2.3 and 2.8 respectively.īut SWR aside, how it performs is the important point. On 80m, the minimum SWR is 1.6, and it is below 2.0 from the bottom of the band through 3.7 Mhz. For 40m it’s 2.0 or less from 7.0 to 7.3 Mhz. Across the 12, 15 and 20m bands the SWR is less than 1.6. The minumum SWR is less than 1.5 on the 10, 12, 15, 20 and 40 meter bands. I checked SWR with my analyzer and on most bands it is excellent. I’ve got the matchbox grounded, and have installed a common mode choke at the feedpoint (which is possibly overkill). The antenna wire is supported at the midpoint by a 32′ fiberglass mast, and the end is tied off to a tree at 35′. The antenna matchbox is installed at the top of a 17′ PVC mast. Plus, the EFHW-8010 can serve as a backup antenna for my hex beam on the higher frequency bands. The EFHW-8010 can easily handle the 600W power output of my amp. Also, I use an ALS-600 no-tune amp and having an antenna with low SWR on multiple bands makes operation convenient. I’ve got 40m and 80m dipoles at my QTH, and combining them in a single antenna was appealing. I spotted this antenna online, and being a fan of end fed antennas I decided to give it a try. Army Military Auxiliary Radio System (AMARS), NVIS * Amateur Radio Emergency Service® (ARES), ALE-Automatic Link Establishment (HFlink), MARS- The U.S. If the transformer box is installed high above the ground, there is no need to route the ground wire from the box, instead just ground the coaxial cable at the entrance to your home or at the station.ĮFHW-8010-1K-Plus typical SWR at 25-30 feet above the ground fed with 50ft of RG8X coaxial cable NOTE: grounding does not affect antenna tuning. *Grounding at the transformer box or end of the coaxial cable is recommended for the protection of your equipment from an electrostatic buildup in order to prevent ESD- electrostatic discharge. 250W continuous in digital modes such as FT8 etc.Grounding of cable at the entrance to the home is recommended.For Pole or tower installations additional installation hardware is available on our “Accessories” page. Measured VSWR in the gallery are taken with the antenna in an inverted V shape with the center of wire at 20 feet and ends a few feet above the ground, your values could vary with the way and height of installation. Various installations such as horizontal, vertical, inverted V, inverted L, etc. *This is perfect antenna for ALE HF-link stations, NVIS, MARS, ARES, EMCOMM etc. This is the smaller version of our EFHW-8010-2K-Plus model, see the comparison image. The average loss of less than 0.4dB is unmatched by any other similar transformer on the market proving our worldwide leadership in the design of high ratio-wide bandwidth RF transformers for 3-30MHz. The antenna transformer is optimized for the lowest insertion loss 3.5-30MHz featuring three stacked cores and a transformation ratio of ~56:1 (~2800:50 Ohms). It is a resonant Half wave on 80m (3.5MHz) therefore also resonant on second, third, and fourth harmonics, etc. Unlike many END FED antennas on the market, this one does not require the Antenna Tuner to operate.
