I keep seeing the odd ref on some other sites to LMR-900UF I even saw it on the online power calculator/attenuation calculator on the times site. But it's not listed on the Times microwave site any w
Nor are the UF versions when making a lot of connections. The jacket is a rubber like material that does not adhere to the braid. This makes the use of regular strippers problematic at best and usele
My software is not working to do this calculation at the moment. What I'd like to know is how much reactance change there is, when going from say 3500 khz UP to 3900 khz. IE: 68' LL rotary dipole res

I doubt solid legs would change the load rating much, but they would be very nice for towers installed in corrosive locations. Does Rohn really make a solid leg 45g tower? John P40A in EU. Trylon mak
Apparently, the UF versions of LMR 400/600 are good for a max of 10 yrs per lmr.... if out in the sun. I know a fellow near Las Vegas who just replaced all his expensive, top brand, good quality dacr

Actually, the transmitter mismatch will be 2.25:1 (112.5 ohms). Additionally, if the "50 ohm" antenna is actually 33.3 ohms, it would be a 1.5:1 VSWR with 50 ohm coax but 169 ohms with 75 ohm coax. Y
