Description
EFHW-8010-2K-Plus, 2000W Multi-Band End Fed Half Wave Antenna
Improved version of the EFHW-8010-2K, now with three large cores, 3-inch diameter, featuring just 0.5 dB Insertion loss 3-30MHz!
This is an End-Fed Half-Wave (EFHW*) antenna for 80/40/30/20/17/15/12 and 10m bands. 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 (3.5MHz) therefore also resonant on second, third, and fourth harmonics, etc. Due to the High Impedance feed point, the antenna is less height-dependent. You can put it up at 10 or 50 feet in the air without much change in VSWR values.
*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 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.
- NO TUNER needed!
- NO counterpoise is needed! (Grounding recommended*)
- Frequency coverage: 3.5-30MHz
- Resonant on 80/40/30/20/17/15/12/10m
- Wire length ~130 feet
- Power Handling: 2kW I.C.A.S
- Digital mode (FT8) 350W continuous
- Stainless Steel Hardware
- Stealth #14 AWG XLPE black wire
- Connector: Silver/Teflon SO-239
- The 2K-Plus model has three large stacked cores
- Transformer MEF-130-2K+ covering 1-30MHz

*Grounding at the transformer box or end of the coaxial cable is recommended for protection of your equipment from an electrostatic buildup in order to prevent ESD- electrostatic discharge.
NOTE: grounding does not affect antenna tuning. 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.

I purchased a Kenwood TS-590SG in January. I needed an antenna to work it with until spring, when I can set up my Butternut HF9V vertical.
After reading some reviews I bought the 8010 2k-plus with no regrets, my other choice was out of stock.
What a great antenna!!!
The feed point is up 18′ the wire runs 115′ to a northeast tree about 40′ up with the remaining wire pointing to the ground, making a stubby “L”. Today I made contacts in Argentina, Brazil, Chile, Dominician Republic, US Virgin Islands and Italy on 15m during a DX contes running 100 watts. Using only the internal tuner as needed, and it wasn’t needed much. SWR was better than expected. Looking forward to using both antennas this summer!
Great Product!!

The 8010 2K Plus is awesome. Built like a tank and incredibly easy to install as a sloper . I was fortunate to already have my UV ropes on both ends so overall time spent was 30 minutes max. SWR readings are as described in the install pdf. I am operating QRP (max 10w) as we speak and just finished a QSL with the net giving me a 59. My next step will be to raise the side of the line to a much higher elevation. Right now its at 25′ so I know the antenna is somewhat compromised. No internal or external tuner operating now
Waiting for my 7300 to really give this EF a run and fine tune using its internal tuner. Again- Awesome and to all- 73 and great DX’ ing

My first EFHW antenna was the EFHW-60S-1k to allow me to work 60 meters. It was receiving so well on many other frequencies (that it wasn’t tuned for) in comparison to my OCF 7 band dipole, I tried this 8010 -2k Plus.
Doing an A-B comparison with an antenna switch, the 8010 receives 3db to 5db better than the dipole and on some bands as much as 10db more on my IC-7610 S-meter. The two antennas are oriented in the same direction and about the same length, so I think this is a good test. They are both about 25′ -30′ in the air.
I’m running FT8 usually and if this antenna is 5db more sensitive, then I’m getting signals now that I was missing before.
As others have said, the SWR is good on all bands, I’m keeping the power low and my received spots are better on this antenna than the dipole as well.
Highly recommend!

I love this 8010 2K & 8010 2K-Plus I have them both and work with them all day long here in south part of Norway
8010-2K I have used for 2 years now and the 8010-2K-Plus used for 1 year and no problem on any of them so I promote for theses antennas for sure – Highly recommend !

Really nice antenna… I mounted my 8010 2K-Plus at 45′ on my 55′ tower and at the 130′ end, it is right at 25′ off the ground. I was really happy to see that when I connected my NanoVNA just how low and flat the SWR was. I have been running WSPR late at night on 40/20 meters @200mW from 10PM to 7AM in the morning with great results. Normal SSB contacts running from 100 to 500 Watts are giving me the same results. I just purchased the 4010 1K-Plus and I’m going to mount that EFHW at the 50′ level of the tower at 90 degrees to the 8010 EFHW.

This is the first antenna I purchased after earning my General and is still the only antenna I use for working HF. I’ve reached 180+ DXCCs (160+ confirmed) working it barefoot with an IC7300. This is a fabulous, versatile, first antenna that provides a great bang for the buck. I can’t recommend it highly enough, especially as a first HF antenna.

I bought this antenna to replace my home brew 40-10…..man it is working great and only 25 above ground! It is in and inverted “L” configuration. The transformer is only about 20 inches off the ground. I am making SSB contacts that I couldn’t even hear before. 7 qsos with POTA stations and 7 dx in fist hour using the antenna with 100 watts. I live in Mississippi.

Purchased in June 2022, installed in July. Now the EFHW8010-2K has been up about 17 months, installed about 30 feet AGL in a straight horizontal line, supported by a Rohn telescoping mast at each end.
Pretty amazing results! VSWR <2:1 for 100 kHz on 80, all of 40m, all of 20m, 17m, 15m and 12m, and about half of 10m. VSWR on 30m is about 2:1. I don't use a tuner with it at all and have put a kW into it (carrier power, tuning up) hundreds of times without issue. I love the very, very flexible but well insulated wire — no kinks, no fighting with you, just lays out perfectly straight with a slight tug and doesn't stretch.
Over 17 months, about 3000 contacts worldwide, using every band except 60m (it will not match there at all).
Excellent value, I'd recommend to anyone.
