S-Meter Lit Black Plugin Backlit S- Signal Strength while receiving and Audio ALC (Automatic Level Control) level while transmitting.  It is good practice to keep the mic audio level in the green ALC area while transmitting. P- Received Signal Strength while receiving, and transmitter power output while transmitting.  ...

G5RV (New Upgraded model)  The G5RV was designed by Louis Varney, who held the amateur radio callsign, G5RV. The design was originally devised in 1946, but it was not until 1958 that it was published when it appeared in the July 1958 RSGB Bulletin. The G5RV antenna is a classical antenna in our series of HS4 Legendary Mult...

Multi-band Trap Dipole   The Trap Dipole antenna is a classical antenna in our series of HS4 Legendary Multiband Wire Antennas. It covers 6 bands, 10-15-20-30-40-80m. This is multi-band resonant antenna The performance characteristics is similar to a normal dipole and is driven through a 50 Ohm coaxial cable and features low ...

W8JK Bi-directional Antenna  The W8JK is a famous and effective DX antenna first built by John Kraus, W8JK, in 1937. Kraus built the first W8JK beam antenna with two parallel dipoles driven with opposite phase, with the unprecedented close spacing of an eighth of a wavelength. The W8JK antenna is a classical antenna in our ser...

W3EDP End fed (10-40m) In 1936, Yardley Beers, W3AWH, described an empirically-derived antenna "designed by the writer's friend, Mr. H. J. Siegel, W3EDP."  It consisted of an 84 foot radiator and a 17 foot "counterpoise."  The design has lasted through the years. .  The W3EDP End-fed antenna is...

Double Zepp The Double Zepp (Doublet) antenna is a classical antenna in our series of HS4 Legendary Multiband Wire Antennas. It covers 7 bands, 10-12-15-17-20-40-80m. Unlike typical antennas, this is a non-resonant antenna. The performance characteristics are quite outstanding. The antenna consists of symmetrical horizontal radiating e...
