Anybody have any good or bad experiences connecting two antennas to one scanner? Example: 1 VHF antenna and 1 UHF antenna. Would they perform better than a single VHF/UHF dual bander?
Are you asking with a diplexer? I ask because I have heard of people trying it with a regular splitter/combiner. I am actually looking at a diplexer for just that purpose. I don't have a dual bander for my needs as of yet.
See here. https://forums.radioreference.com/threads/antenna-for-military-and-civilian-air.381736/
There are cheaper diplexers out there. Just search uhf vhf combiner
I am not sure if a dual bander tuned for your freqs of interest would be better than a diplexer with 2 separate antennas tuned for your freqs of interest. So I will also be watching this thread.
I was thinking about 2 separate antennas and a male BNC plug with dual BNC female plugs. I think maybe that's not the way to go about it though. The only bands I will be monitoring is VHF hi and UHF only.
Yeah, that's what I was gonna tryif just receiving, give it a try.
there are no rules, just what works for you.
i have done it with a radio shack 800 antenna and a motorola 150 rubber duck.
with no equipment i could not tell a great difference.
both antennas vertical, each into a 90 BNC, into a tee connector.
experiment and have fun
Thanks for the infoThe diplexer I linked to introduces only <0.6 db insertion loss. Any other methods will be 6+ db loss.
You are correct i posted the wrong link. I will post the correct one later.That's a duplexer, not a diplexer. Many will argue they're not the same. As I uderstand it, a duplexer is used to connect one antenna to two radios, where a diplexer is used to connect two antennas to one radio. I'm too tired to argue...and dinner is ready!

This is the diplexer setup I use in my vehicle. It allows me to use dedicated mono band antennas on various parts of the radio spectrum, as well as multi band antennas at each port. In my case as a Ham, I especially like having HF and 6 meters split, as well as the VHF/UHF separate from the 840 MHz public service bands. In the case of a base station receive only scanner, the diplexers could be housed in a weatherproof container and fed with a single high quality coaxial line. The small insertion loss of the diplexers is more than overcome by the ability to optimize the antennas on each band.View attachment 67832
You might shop for an Austin "quadplexer' or "pentaplexer" which can have separate inputs for up to five different bands. I have several I picked up off Ebay that combine all sorts of frequencies.
You absolutely can do that. If you only have one VHF antenna that you need to connect and 1 UHF for 800 megahertz and that you need to connect you simply purchase a diplexer. I like Diamond.Anybody have any good or bad experiences connecting two antennas to one scanner? Example: 1 VHF antenna and 1 UHF antenna. Would they perform better than a single VHF/UHF dual bander?
