Efhw sloper
WebPar EndFedz® Antennas are low-power End Fed Half Wave (EFHW) antennas with the match box coax connection at the end of the wire, for convenient and quick stealth portable operations. These single-band and multi-band antennas can be mounted horizontally, vertically, or as a sloper. WebOptimally deploy the antenna as a sloper with the high (feed point) end at 30+ feet and the low end at 10+ feet. ... If you find that common mode exists after you install the EFHW antenna, attach a Grounded Counterpoise to the barrel connector at the antenna feed point, then secure with a stainless-steel hose clamp.
