Hello, I just recently got a HP-2 since my local system is upgrading to a P25 and I was just wondering does anyone like another particular antenna rather than the stock one?
Thanks in advance,
Bradley

Are you looking for an external antenna or one to attach directly to the scanner the same as the stock one?
One to attach directly would be great 
I have a couple telescopic ones, they're not very expensive and have worked well. Public safety in my area is around 150mhz, which I believe you would set the antenna to rougly 18". https://www.amazon.com/Bingfu-7-Sec...c+antenna&qid=1605036601&s=electronics&sr=1-4
I've used this site before (or one similar) to calculate how tall the antenna should be for any given frequency. And I use the bottom formula for quarter wavelength. Whip Antenna Length And Frequency Calculator
I've had good results with this antenna:
It's a telescopic antenna, as is the one doovenator suggested. It does have a swivel base so that you can adjust the antenna to be vertical. It also has frequency markings on the antenna itself to suggest how much to extend the antenna for a specific frequency range.
It's also available with a BNC connector (you'd use the SMA to BNC adapter that came with your HP-2) as well as an SMA version where you would not need the adapter.
