Laird Question About 2 New Antennas For My Uniden BCT 15X Scanner Used Elusively For Mobile

[CityNewsSupport]

Hello All
I am looking to replace an Aging Antenex C40 I use to pick up the California Highway Patrol and A Junk Amazon buy for all other Frequency! I Run A Uniden BCT 15X I Am considering the following

A Laird 150-450-800 Scanner Antenna Black (ABSCANC) Or a Larson Triband Off Amazon
A Laird 40-47MHz DC Ground Base Load Antenna Black Chrome (C40) For CHP Is this still an Appropriate Antenna To Replace The Antenex C-40? (I Was Assuming it's the same I do not recall the specs on the Antenex as I bought it 22 years ago)

I am also open to recommendations Thanks

The two Area Offices I monitor For CHP Are Solano & Napa

42.42000	WPHM437	B	103.5 PL	GRP2 GAT B	Grape 2 - Base - Napa (21)	FM	Law Dispatch
42.66000	KA4993	M	103.5 PL	GRP2 GAT M	Grape 2 - Mobile - Napa (21)	FM

42.60000	WNUH519	B	131.8 PL	TRQ GAT B	Turquoise - Base - Solano (22)	FM	Law Dispatch
42.02000	KA4993	M	131.8 PL	TRQ GAT M	Turquoise - Mobile - Solano (22)	FM	Law Dispatch

I use this one on my truck and it works really good for me. It is similar to the Laird. https://www.amazon.com/Larsen-NMO15...00+Tri-Band+Nmo+Antenna&qid=1581656112&sr=8-1

I originally bought this one thinking I would use it on my truck but it was too big and cumbersome looking so I ended up using it inside and it does really well also. Not one you are looking at but it also works well for me. https://www.amazon.com/Browning-Tri...00+Tri-Band+Nmo+Antenna&qid=1581656112&sr=8-5

The Tri-Bander (either Larsen or Laird) would work well. The low band whip for CHP is a great addition. Larsen or Laird would be fine.

Important part will be coupling both antennas to a single scanner. Simply T-ing them together isn't necessarily going to work. I'd recommend a suitable diplexer.

The best mobile antenna for CHP is the antenna the CHP uses, a wideband 37 to 42MHz CWB42 series. NMO mount and no tuning needed to cover 37 to 42MHz. Couple that with a Larsen tri-band or Maxrad BMXSCAN1000 with a diplexer and you will cover just about anything. Well anything but VHF air and UHF air. Ok, maybe it will miss a lot of stuff, but it will look really cool.

What diplexer would work with that? The triband covers a large spectrum of frequencies. Do they make diplexer to combine the triband with VHF low?
