On my Ham radio set i have a device that splits from vhf to uhf, you screw both antennas into it and it switches over when you use which ever band.

Why not just use a discone?

I use a ham band vhf antenna for listening to the air band it works perfect even though it’s designed for 144mhz the air band stops at 137, i also use it to listen at 220mhz military it works there too.

Just another thing for best results get this antenna outside on a pole off the chimney, Or the wall the range you will receive will be further it’s line of sight.
