WHA01 WIDEBAND HF ANTENNA

15Datasheet Release n 01

OVERVIEW

FEATURESMinimal maintenance requirements

High Reliability suitable for tough environment

No tuning devices

Low SWR

50 ohm coaxial feeding line

High RF power continuous duty

Rugged epoxy-fiberglass whip elements

Aluminum mounting hardware

PRELIMINARY DATASHEET

The EASP-WHF01-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-VHF01-ANT operates in the 2 MHz to

30 Mhz frequency range providing a typical

return loss of 10 dB minimum (SWR 21)

Working principle is based on a unique design of

coupling the low output impedance of the tran-

sceiver (50 ohm typical) with a high impedance

vertical radiator A fully passive network made of

a mix of lumped and distributed elements is

employed in order to maximize eciency and

mantain reasonable losses The radiator element

is galvanically short circuited (DC) with ground

in order to assure suitable lightning protection

PN EASP-WHA01-ANT

The EASP-WHF01-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 pattern are avai-

lable as well
