Description
EFHW-8010-LP- 250W
Portable or Stationary Multi-Band End Fed Half Wave Antenna/
This is a 250W version of the popular EFHW-8010-1K+ End-Fed Half-Wave (EFHW*) antenna for 80/40/30/20/17/15/12 and 10m bands. Featuring an optimized MEF-130-LP transformer with an average insertion loss of only -0.4 dB (~9% loss) compared to similar products on market with insertion loss as high as -1.5dB (~30% loss). Unlike many END FED antennas on the market, this one does not require the Antenna Tuner to operate. It is a resonant Half wave on 80m (3.55MHz) and therefore also resonant on second, third, fourth, etc. harmonics.
*This is perfect antenna for ALE HF-link stations, NVIS, MARS, ARES, EMCOMM etc.
Various installations such as horizontal, vertical, inverted V, inverted L, etc. are possible. Measured VSWR in the gallery are taken with the antenna horizontal at 25 feet above the ground, your values could vary with the way and height of installation.
- NO TUNER is needed!
- NO counterpoise is needed!
- Frequency coverage: 3.5-30MHz
- Resonant on 80/40/30/20/17/15/12 and 10M
- Wire length ~130 feet
- Power Handling: 250W I.C.A.S
- Digital Modes, FT8 100W max.
- Stainless Steel hardware
- Stealth #16 AWG black wire
- Connector: Silver/Teflon SO-239
*Grounding of the coaxial cable at the radio side is recommended for the protection of your equipment from an electrostatic buildup in order to prevent ESD- electrostatic discharge.
NOTE: grounding does not affect antenna tuning.

I purchased this antenna for use for CW at our Field Day. I just pulled it out of the box and put it up without looking at the analyzer. The antenna was put up far short of the ideal height, more like 15 feet at the lowest point.
The results were superb. The TS-590SG tuner had no problem tuning it up on the 80, 40, 20, 15, and 10 meter bands. We made many contacts on CW, including Hawaii, Puerto Rico, and the U.S. Virgin Islands.
I plan on using it again for Winter Field Day next January. Then I will get it up much higher and will be eager to see how much better it does at 30 or more feet high.
At any rate, I see no reason to deal with beams and “portable” compromise antennas at FD. Just put up one of these EFHW antennas and have an outstanding event while not having to fiddle with the antenna each time you change bands.

Very happy with this antenna. Its my first HF radio so I wanted something that would be reasonably priced and allow good performance on several bands to gain experience. The 8010 LP has exceeded all expectation and the multi-band ability has really shown its worth. Contacts out to ~6000 miles with just 20 watts on multiple bands are common. If the band is open the antenna is up for the task. SWR is great and the antenna is easily resonance tunable to really tailor it to your use. No need to cut the wire either so if you install somewhere else at a later date or just want to fiddle with it, all is well.
It is however very long at 130′ so pre-planning is a must. I have found it to be very tolerant of imperfect installation. If you’ve got to redirect it to make it fit, you’ll likely still be happy.
Bonus: 160m does tune up work with my internal tuner.

Mounted with feed point at 10m sloping down to 2m. Tuned on every band. Slightly more noisy than a dipole (on 80).

These are amazing antennas. I have two that I am using for base stations and purchased two more as backups. They are resonant on 10M through 80M, and will tune 30M with an internal antenna tuner. Highly recommended!

Great build. Attention to detail. Can you make one…sure.? Will it be as well done when they make hundreds or thousands? ???? I’m happy to spend the money and leverage that experience for myself.
Chris –
Great antenna! Tunes easily on all bands except
160m. I usually run my 7610 at 50 watts and have made good contacts all over the country and a few South America stations. Easily worth the price.

We are just getting our feet wet in ham radio, hence the 4 rating. We are only monitoring ATM, no transmissions just yet. We did hear a gentleman from Cape Town, South Africa a couple of weeks ago. The shipping time was lengthy, but we ordered right before Hutricane Helene moved through, so the extended ship time was TOTALLY understandable. When we start transmitting, we will revisit the rating. We have heard good things, so that was a factor obviously in our purchase.

These are great antennas! I use them as my base antenna, and have one installed on some property we own. SWR is less than 2:1 across all the bands the antenna is rated for. Get one (or two!). You won’t regret it.

The EFHW 80-10 works great, up about 40 feet, use it for POTA, AT 5 watts as a hunter. I always get good reports, and even at 5 Watts, I always make the contact. This antenna is flat at all frequencies and works better than expected.
Jim Thompson –
By far the best antennas I’ve used ! The ease of setup makes it perfect for any application.
Michael C. –
Excellent antenna so I have two of them
David C. –
Unit worked well for 2 months and for some reason yet to be investigated, 10 and 20 mtrs is no longer working.
Danny-E73M –
Probably you had too much tension and wire stretched shifting the SWR below bands.

I have this antenna for about two years now, and I made lots of DX QSO with it. I never had a problem to log a rare DX, and many of them they coming back at my first call. I feed it at 8ft high runs 45deg angle up to a tree top at 40ft, then runs across the yard up to an other tree top at 60ft high. My back yard is about 90 ft long. I only run 100W. I made DX contacts on 80m in to EU, but only in contests, and just a few of them. The antenna really works from 40m and up.. 80m is great for NA. You can hit me up on QRZ.com as KV1I see my Clublog, or QRZlog. I only work on CW, and have many rag chew on all bands. I work with stations in to VK/ZL, EU,AF,AS,SA, and NA. I made DXCC100 in no time. The antenna is easy to erect, and you can use any kind of configuration, as Inv V, Inv L, Flat top, Slope, Zig Zag. However you can put it out. The main thing is, put it up as high as you can. SWR is pretty good on all band, although it should not work on 160m I tuned it with my Ten-Tec Omni VII internal tuner and had a couple of local QSO
😉 It really does work fantastic.

It was a gift for a friend, idk if he set it up yet….

I’ve actually bought 3 MyAntennas EFHW antennas. The first (a high power unit) worked so well that I bought a second for my EmComm kit, that one I gave to a friend just getting started in Amateur Radio so I bought a third (this lower power unit) to put back into my EmComm kit! Great antenna and when tuned to resonance on 80m doesn’t need a tuner on any of the HF bands. It is my primary “go-to” when the bands are noisy.
Dave Jones –
SWR is good across the promised bands. My antenna layout is far from ideal, but I’ve made great contacts and am happy with it.

Have a modest old rig with a qrp tuner works great and allows me to move around bands during this time in solar cycle
John Held –
Excellent antenna. I have one up here at the house and use one for Field Day and other activities. They work as advertised and have never let me down. I have always experienced low noise levels with their antennas and always have low swr readings. Highly recommend their antennas for a permanent setup or for use in the field.
David N. –
Really like the end fed 10-80. Performs better than expected.
Will buy another in the next year. Will not look anywhere else. Will buy the 10 – 75 model.

This antenna blew me away. I installed it 16 feet above ground in an L design and I work the world on two hundred watts.i enen get through pile ups. Only thing I wish is that it was a heavier gage will since I have a lot of movement when the wind blows hard. Would I buy another one? Hell yeah!
