Hi guys, I am just looking at this signal booster on amazon, it is designed for 3g and 4g cell phone signals. it says in the description that it will go from 698 to nearly 2700 mhz, and give up to 6db Of gain. Do you think this would work for p25 , I'm wanting to put up an outdoor antenna for my bcd436hp but I'm not sold on a discone. Any thoughts of experience? Thanks in advance.
