so i recently installed a uniden bcd996xt scanner to compliment my motorola cdm1250... (in my tahoe if i failed to advise) now... i did not feel like installing an antenna on the roof becuz of holes, drilling in roof, water leakage, etc, etc. so i went with the old fashioned dukes of hazzard and put a ball mount spring antenna on the left, rear quarter panel above and left of the gas cap. now my problem is... with the 102" antenna, it works excellent monitoring the p25 nebraska state radio network along with other analog public safety frequencies. the thing is, i cut the antenna down from 102" down to 74" or just over six feet (down from 8.5 ft) now the signals whether analog or p25 cut out while moving. stationary is just fine... 102" great... 74? not so much. any ideas on how to correct or solutions without sporting a 26 foot antenna that practically reaches the moon? that is/was the only mod that i did that caused the change that im aware of. i can tell when the antenna weaves or bends or whatever u call it on the p25, the signal bars can easily go from 5 down to 2-3 bars if im lucky. thanks in advance!!
