I see alot of talk about what antenna to use, does this antenna work better than?? ect.
Really simple project that you all should do is make your own "dipole" antenna and it's very easy to make. If you don't want to bother how antennas work here is easy way to make your own dipole antenna and spare the technical part. Just remember that antenna is resonate at a specific frequency. So a 154 Mhz antenna will not be very good at 770 Mhz ect.
With that said he is a very cheap and awesome dipole antenna that I made in 2 minutes.

And then grab any wire it can be any wire, I used some black stranded 18 guage wire I had laying around and cut it 2 pieces 2 7/8 of an inch and you have a resonant antenna at 750Mhz. And yes we checked it on a Rig Experts 1000.

You can cut the length of the wire of both sides of the dipole for any frequency you want to get the best reception on that frequency you want to use.
Just make sure each side of the wire is the same length and to determine what length to cut for a specific frequency use this simple dipole calulator.
Just plug in the frequency in the calulator and use the bottom box in the calculator "Quarter Wavelength in Inches" for each side of the dipole.
Hope this helps, especially for people on the simulcast systems as this antenna is amazing on the EBRCS system in the San Francsico east bay area.
