Wideband HF Antenna


The OMNI-A0354 is a HF Whip antenna. The antenna has an integrated matching circuit to passively match the antenna to the transmitter/receiver. The antenna includes 4x ground radials to act as counterpoise. The antenna Gain and VSWR as depicted are with a counterpoise (ground plane) consisting solely of the provided radials. VSWR and Gain could improve with practical installations over actual ground or mast counterpoise conditions.
