I am looking to see if I pick up more traffic if I upgrade my antennas on my scanners, I am new to this and I am running stock antennas currently on the P-25 System for hancock and shelby county indiana.
Most of my listening is 500MHz with some VHF-Hi and I haven't found anything that improves reception noticeably over thee factory antennas shipped with my 436 and HP2. I did pick up a custom built antenna off eBay made specifically for the HP and it does a good job so I keep it installed. Is it better than the original? Maybe a dB or two, but not noticeable to me.
