Hi All
On my duplexer The High port seems to be faulty.
I have an additional antenna so I was thinking to use the LOW port of
the duplexer with the existing antenna (because on the same tower a TV
station is having its TX antennas: output power 250W, Police repeaters,
Civil emergency repeaters and so) as receive and the other antenna
directly on the TX radio as TX antenna.
The tower is 25 meter high. And on the top of it are the TV antennas
installed.
Is there any formula to calculate the distance between the antennas
(vertical and Hor) for proper isolation?
The antennas are Procom UHF CXL2XXX series
Operating Freq is RX 443Mhz TX 453 MHz
