Need recommendations for p25 antenna to monitor a system 25~30 miles away on SDS100

I have 3 different Remtronix antennas for my SDS100 (7/8/9 monobander, 7/8/9 + UHF, and the tri-band 843s) the 820s is the best of the three for 7/8/9 by about 3dBm over the dual bander and 5dBm over the tri-bander. I haven't found anything more effective than the 820s for portable use on 7/8/9. For that kind of monitoring, I think you're going to need a true mobile or base antenna.
Perhaps a Smiley or other higher-quality makers have an antenna that would improve your reception.

You need to look seriously at an external antenna, if there's any way to do so. Or, try getting a Yagi you can mount inside your house as high as possible in the attic or near a window.
Listing the freqs of interest may yield better recommendations. P25 does not mean anything.
I'm assuming he's talking about a 700/800 system, because of the antenna model mentioned, and because it's required in 700 and de rigeur in 800 most people conflate 7/8 with P25.
P25 is real nice on VHF conventional, too. I wish there were more of it on VHF and UHF.

You're going to need an outdoor antenna, perhaps a yagi pointing towards the direction of the (assuming) 700/800mhz systems 30 miles away. Also without knowing what topography is like between you and the destination tower(s) it's uncertain you'll get any reliable pick up at all. 700/800 doesn't propagate as far as VHF/UHF. Also it may help to experiment with the different filter settings

he has mentioned Georgetown and Austin TX.
might be that.
