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.
