Mike, I have a site where the
224 on the VHF repeater is now about 3 feet from a T mobile antenna.
Today, the cell electronics, including RF is up on the tower. The boxes
are fed with 48 vdc and fiber. If I run 40 watts of RF on the MTR-2000 I
have over 40 dB of desensing. I am running 1 watt right now which brings
me down to about 10 dB of desensing. In a month of two I will have a
tower climber look around for me. I am planning on installing a huster G6
as a transmit anteena, on the other side to the water tower ( the antenna
will be clear of the water tower "dome". There will be no cell
antennas close to it.
I have a telewave 6 cavity duplexer, that into a dummy load has no
desense. None. I am convinced that my 147 MHz RF is into the broad band
amps, and they are doing a wonderful job of spitting it back. I cann't
yell at them ,they pay rent!
When I first moved into my home in the late '90s I could not operate a 2
meter repeater from here: switched mode power supplies in cable TV set
top boxes in the neighbors' homes would mix my output to my input.?
Then streaming happened & everyone got rid of their STBs, & now I
can duplex on 2 meters but now the noise floor from LED street lighting
makes the repeater deaf at night.
