So here is a tricky one for you all to chew on.
I purchased a couple of yagi antennas for Mass State Police freq. I put them up at 90 feet on a tower pointing direct at the appropriate troop sites (Milton and Middleboro). They were first connected to LMR-4-50. No trunk signal “T” nothing. OK so maybe I had bad cable?? I run new RG-6 still no signal. OK bad antennas?? So I take radio (RS-197) up to 90 feet and connect 6 foot jumper of LMR-400 to antenna(s) and radio. Still nothing heard and no “T”. Disconnected antenna with just 6 foot jumper plugged into radio at 90 feet came in loud and clear. R-9+
Stymied now back on the ground. I connect yagi to 6 foot LMR jumper point in direction of Milton. Nothing !! Now I am pissed I set yagi on the ground works fine. Put on 6 foot PVC and hold it in the air, nothing. I am like WTF is going on here!! Works on the ground but not in the air?? Just for shorts and goggles I connect a Tram 800 NMO antenna. Set on the ground works fine. Touch the ground teeth to tower nothing. Taped it to PVC put 6 feet in air nothing.
This entire event is so counterproductive to what I know about radio and radio signals. I am pulling my hair out of my head. Took down LMR, RG-6 packed my stuff in my truck and called it a two day failure.
Any suggestions??
