ko propo ex 5 transmitter question

The receiver that originally came with my ex 5 transmitter had the antenna break off during a wreck :( tried soldering it back on and i'm only getting 30 to 50 feet of range now.

Tried hooking up a different receiver which was completely non-responsive when I use my ex 5 tx. when I use another tx the new receiver works.

Basically I'm wondering if there are some receivers and transmitters that don't work together even though they run in the same frequency. And if anyone can recommend a new rx to get for ex-5 transmitter.

if you get some signal but a short range, this means that it isn't a compatibilty issue, but rather a signal one... could be coming from the TX signal (antenna holder not soldered properly to RF board) or from the RX (the obvious suspect being the antenna here too, but sounds like you have this covered).

there's soooo many things that can go wrong on a vintage radio :(

Good luck

My next question then. Is there a specific receiver I need as a replacement? I have a sneaking suspicion that the receiver gave up the ghost.

you haven't even specified what model RX you're dealing with

also "EX 5" name has been around several generations,
from first AM model to the latest EX5 UR with fancy 2.4g
- what vintage is yours?

Because you are still getting a signal to your vehicle, this means your radio still works. The shorter range is because you generally cannot repair an antenna. If you can just get a replacement antenna for the radio you have, I think that your range problem will be solved.
As for trying different radios, keep in mind that not all radios are compatable. KO will not work with Futaba or Airtronics, after all, Ford does not want Chevy putting parts on their cars. Crystals are not interchangeable between manufacturers either. You pretty much have to stay within each manufacturers own equipment line.
