Okay, so I got a new antenna after my old beat up Radio Shack discone had only two radials left from about 25 years of use, I got the Diamond D130NJ and put it up today, very disappointed in the 800 P25 bands compared to the old antenna, every other frequency is awesome and a huge improvement, it is so noisy in the 800s even with Attenuation on the TRX-1, crackling and popping. What can I do to fix this, any pointers?
