Understand that TV vs typical scanner freqs. are different. Was using the TV type kit as an example. In and ideal world I would like a unit that is wideband from say 500kHz to 1GHz, two antenna inputs (up to 200MHz and 200MHz and over. I've not done much additional research on this.OTA TV signals and scanner signals are on different antenna systems. At home each is amplified and distributed as needed. When mobile, I have more than one antenna on my vehicle; one for each receiver.
As a side comment I'm into LW/MW/SW (30kHz to 35MHz) and Airband in the main (100MHz to 140MHz). My long wire antenna is absolutely brilliant at Airband when compared to my airband antenna so I essentially just run on the long wire when at base.
