The advantage of an EFHW is the ease of construction, it’s versatility in a variety of installation configurations (sloping, horizontal, L, etc.), no tuner is needed, and this one works on 4 bands: 10, 15, 20, and 40 meters. We chose a 250-watt rated antenna so you can comfortably transmit the full output power from many off-the-shelf HF transceivers (typically around 100 watts).
Building the kit is easy. You’ll drill, fasten, and solder (a small amount). Most everything goes into the included weather-proof box. Admire, then deploy!
Who needs this antenna?
New licensees. Build something, and you’re no longer a licensee…you’re a ham!
New HF operators…and anyone seeking an antenna that covers the bands that will become increasingly active with Solar Cycle 25.
Experts…because you’ll appreciate a quality kit, and you’ll end up with a great antenna you can take with you anywhere (think vacation).
