I've gone through quite a few Antennas on my PSR-800 & 500 scanners trying to find one that pulled in signals from not only my city but the ones around me. I finally found a beauty and figured I'd pass this on, in case anyone was waffling on it or just looking for a darn good antenna. I got the 800MHz 2.5db gain Professional Portable SMA Antenna from Scanner Master, and I finally found a little slice of heaven. I have tried the GRECOM (nea RadioShack) 800MHz antenna and it was decent, but this thing sucks in the 800MHz signals like no ones business I've finally found antenna nirvana. It's not as inexpensive as the GRECOM/RS antenna but it outperforms it in every way.
If you own a PSR-800/500 and are thinking about getting one of these, I highly recommend you get the SMA version then obtain a BNC to SMA adapter (I got mine from Amazon because Scanner Master didn't have one that I could see). Apparently the BNC version of this antenna caused some angst with PSR-800/500 owners and the BNC jack on the radio. I just avoided the whole catastrophe and used the adapter (I can also attach my ham radio antennas this way too, though ironically the arrow II uses bnc...). I'm not trying to sell this antenna and have no affiliation with the maker nor Scanner Master but this is just a dang fine antenna for 800MHz.
You can have a peep at it here: https://www.scannermaster.com/800_MHz_2_5db_Portable_SMA_Antenna_p/14-541014.htm
