EFHW-4010-LP- 250W

Portable or Stationary Multi-Band End Fed Half Wave Antenna/

This is a 250W version of the popular EFHW-4010-1K+ End-Fed Half-Wave (EFHW*) antenna for 40/20/15/ 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 40m (7.1MHz) 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.

    Took a hot minute to get it high enough to get an acceptable swr, but I got it. It’s about 11-15 feet off the ground in an L configuration. Began picking up signals right away and made a contact on 40m ssb soon after. For the price it’s hard to beat. Just be patient, it can take a minute to get it right.

    Great antenna!
    Well made and easy installation. In addition to designed 40m through 10m, I can tune 80m and 6m using a tuner. Perfect for HOA restricted neighborhoods. Highly recommend MyAntennas.

    This is my 3rd MyAntennas product. So why do I buy so many antennas because I have different needs and I really like the quality of the product. You can’t go wrong when you buy a buy a MyAntennas product.

    End Fed 40 – 10 meter Half wave connected to Elecraft K4 w/ 10:1 auto antenna tuner. Antenna is hung from 3 ft wooden dowels standing off from my rain gutters, only up about 13 feet. Makes a jog around, not in a strait line. Never trimmed, hung as delivered. Works on all bands as advertised!

    I decided to purchase this antenna because I was looking for a multiband antenna that was economical. The no tuner needed was the main selling point. I’ve been using it for a few months now and could not be anymore pleased with its performance with contacts on 40m,20m, 15m & 10m. I have the xfmr end mounted on a tower leg at 40 feet with the end of the wire tied to a tree about 20 feet up. BTW the first attempt to use it I made a contact on 20m and received a Q5 signal report with Switzerland running 100 watts.
