I dont know much about base antennas, just HT antennas. Can i run multiple scanners off of 1 antenna by utilizing splitters bought at a local radio shed? If i do this, will performance be hindered?

Can i possibly use a CB antenna i have on the same mast for local vhf monitoring?

I am currently running 1 scanner on my antenna on the mast, and the rest on rubber duckies or stock antennas that came with the scanner.

Any help would be great.

You will normally lose 3db per connection with a splitter, I wouldnt split it more then once. Depending on how well you can receive the system this might be acceptable for your application. If you want to share one antenna for more then one radio the best method is to get yourself an active mutlicoupler. You can pick them up for around $100 on eBay (make sure you check the freq range). I share one antenna amongst 8 rx radios.

Something to think about. If the antenna on the mast is not cut for any specific freq and you used RG-58 coax, then youve gone backwards. Because the antenna is outside does not make it any better. You can double your capture area on a portable by using a Gold Post BNC adp and using the same ant's on each connector. THEY MUST BE THE SAME or their will be a mismatch if one is UHF and the other is VHF. I've used two [2] factory ducks on a Gold Post and it really helped. If you dont know what a Gold Post is, look here. www.bncantenna.com

Hi Junky and all,

"Can i run multiple scanners off of 1 antenna by utilizing splitters bought at a local radio shed?"
Yes.
"If i do this, will performance be hindered?"
Yes.

Look into amplified couplers, preferably one with unity gain. Too much signal will overload the receiver and cause reception problems.

"Can i possibly use a CB antenna i have on the same mast for local vhf monitoring?"
No.

Larry, what the heck are you talking about? Every antenna is cut for a specific frequency or frequencies. You're right about the RG-58U coax, except for very short runs in the mobile it's useless above 30MHz. What could you possibly mean by "capture area"? We're talking antennas here, not sail boats. Mismatch of what, connectors, impedances, frequencies, bands, what? I checked out that site and still don't know what a "Gold Post" is, perhaps linking directly to it would provide a clue as I'm not about searching the entire site for an antenna, connector, adapter, some kind of coax or whatever this mystery object is.

Speak clearly, I hate it when you mumble.

I hate coming down on guys like this BUT if they can bamboozle me with 30+ years of radio communications experience I can just imagine what frustration casual scanner enthusiasts go through trying to untangle the mess. Cummon people, PLEASE get it together or ask a few questions of your own before passing along misconceptions, misinformation, improper terminology and other brain dingleberrys you picked up along the way.
