Stacking Transformation
The ideal impedance transformation ratio are actualy ZL = 50 Ohm and ZI = 100 Ohm, but to get this ideal impedance transformation means that for TR, we must use a coaxial cabel with a Characteristic impedance Zo = 70.71 Ohm
Super facil antena vhf 1/4 onda
Antenna Ground plane (GP) has the property of receiving and transmitting in an omnidirectional way, that is to say everywhere equally
Super J-Pole Collinear
The antenna J is very simple in construction and has good results
T-match for vhf -uhf Antennas
The T-Match with its balanced feed point is one method of feeding a Balanced Dipole
Antenna Yagi 11 Elements
After using the charts according to DL6WU, the following values have been encoded for the calculation

Antenna splitter per VHF-UHF per quattro ricevitori Chi dispone di una sola antenna e vuole collegarvi più di un ricevitore necessità di uno splitter
Amateur radio kits by Kanga US
50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
