Dipole and Inverted Vee Antenna Calculator

The basic formula for determining the wire length of a center fed, 1/2 wave wire dipole or inverted vee antenna - 30 mhz or less is 468/freq-in-mhz for feet and inches or 143/freq-in-mhz for meters

13 CM transverter Here it is shown connected to a 120w amplifier, which is sitting on top of it.This transverter can deliver about 25w on it's own, and runs on 12v, making it suitable for portable service. When at home with 28v available, I use it with the 120w amp.It's a hybrid, and consists of a basic DEMI transverter board kit, a driver board out of a Spectrian amplifier, and my own T/R control board
