  1. So this is what I got, on the rf side of things... Motorola Radius M1225 UHF 20-40watt ID o Matic controller RG-214 jumpers with N (non magnetic - nickel free) connectors LNA from Downeast Microwave GaAs Phempt >17db gain 0.5db noise figure. Harmonic Preselector 3 pole - 1.2 db loss - pulled from a Motorola MTR2000 brick Vertex 6 cavity XUFIP0001 notch duplxer . 40watts in 37watts out on my meter. 50ft of DX Engineering 400max to a slim jim 3/8" copper - mounted on a 40ft fiberglass mast - away from all things metal... My question Should I add a Low Pass Filter? I kinda want to.... I've used them before on vhf transceiver's and have had great success in the cell tower jungle of Brooklyn.... BUT...Is there a point where more becomes less.....in line to the receiver My neighborhood did just get new 800mhz cell towers in the area. About 1/4 mile away.... I have a LPF pulled from a GE Harrison repeater (432 - 470mhz). Can't find specs for it. Don't know the db loss... I am looking forward to experimenting.....but due to my situation, I can not run around with an ht right now... Plus I have learned on my own and would like to hear from people who actually know what they are doing and can add to my knowledge... thanks d
