The EASP-WHA02-ANT is a wideband HF vertical antenna, mainly intended for use with ALE and frequency hopping capable transceivers, for HF radio voice and data communications.
The EASP-WHA02-ANT operates in the 2 MHz to 30 MHz frequency range, providing an average return loss >10 dB (SWR 2:1). The working principle is based on a unique design of coupling the low output impedance of the transceiver (50 ohms typical) with a high impedance, vertical radiator. A fully passive network, made of a mix of lumped and distributed elements is employed to maximize efficiency and maintain reasonable losses. The radiator element is galvanically short-circuited (DC) with the ground, to assure suitable lightning protection.
The EASP-WHA02-ANT is a self-standing whip antenna made in epoxy-fiberglass with an aluminum mounting base. The mounting base utilizes the standard drilling template used for shipboard antennas. Custom drilling templates are available as well.
