I have two Wilson Trucker Antennas, I would like to co-phase them together with the 3W amp in-line. I've not been able to locate any "T" and/or adapter to run 2 cell antennas. Is there a simple "T" connector so this could be done?

There is not a “T” type connector available in the FME male.

I would not recommend using two antennas combined as you may damage your inline amplifier.

I was also looking for this topic.
Expect a permanent solution later.

I'm not a radio engineer, just an enlightened user - but even I know that's not going to work like you think it will, unless you know a way to disable the laws of physics.... It'll probably make it worse, and likely blow up the booster amplifier.

Cellular is in the 800-900 MHz and 1800-1900 MHz bands, and the distance between the mirrors is all wrong - the VSWR is going to be all over the place depending on the channels the cellular system chooses for that area. Plus, these trucker antennas are self-ground-plane, meaning the vehicle body shouldn't be as big an issue.

Co-phased antennas DO work on CB's because the average truck cab is just the right width, 1/4-wavelength apart at 27 MHz ~102" - ~106" apart. And the co-phased antennas cancel out the effects of being hung off to the sides of the vehicle body ground plane, putting out badly mis-shaped transmission patterns with huge dead-spot and hot-spot lobes, where the plot drawing looks like a huge cauliflower instead of a nice neat mostly omnidirectional pattern.

Use one cellular antenna. If you really need the dual look for a Show Truck get a real set of CB Twin Truckers for the CB on the mirrors where they belong, and put the cellular antenna off the back of the cab or behind the wind deflector, centered. Or get someone to make you a dummy Cellular Trucker antenna for the other side - fiberglass whip with no wire inside. Then it'll look balanced.
