Wideband HF antenna 1,5KW PEP

The EASP-WHF1K-ANT is a relative high efficiency broadband vertical radiator intended for use with frequency agile
transmission systems over the 2 – 30 MHz HF band (i.e.: HF/ALE systems).
It is produced in two different versions, respectively :

  • EASP-WHF1K-ANT/R for the roof mounting solution
  • EASPWHF1K- ANT/N for the naval mounting solution 

Working Principle
A vertical radiator can be matched to a 50-ohm feed line by an inductive (L), a capacitive (C), or an L/C system. An HF
line with its end, either open or shorted, can be an “L”, a “C”, or an “L/C” matching system, depending on the ratio of its
length to a given wavelength. A coax stub can therefore replace most matching systems.
