I am thinking about getting a new scanner but only looking at paying about $250. I mostly listen to Trunked Fire and Ems freq’s but also listen to fire in the 400 MHz range. I also listen to aircraft and military band. I am mostly an amateur but want a scanner that I could sort of grow with. Also what antenna would you recommend I will need to keep it indoors since I live in an apartment on the bottom floor. Thank you for the help.
