Hello!
If there is anyone out there who would be willing to assist me with a balun design for an FM transmitter antenna I would appreciate it.
I have a transmitter that is power output adjustable between 1mW and 25mW and was hoping to make the antenna as efficient as possible, thus running the transmitter with as little power as possible while still being compliant with the laws in my part of the world for a license-exempt broadcast.
I've found many websites in my searches that discuss baluns, but it seems the breakdown of information from google searching falls into the following categories:
90% of sites say "you should use a balun to balance the antenna" or equivalent statements
9% of sites try to sell an antenna with a balun as part of a kit
0.99% that give generic instructions for making a balun (e.g. "wrap the coax 5 turns", "wrap some wire around a ferrite core", etc)
1 website that gave specific instructions on using a piece of λ/2 coax to make a balun but in the context of a "closed loop" dipole(?).
If anyone has any specific instructions for making a balun that will work with a basic half-wave dipole I would appreciate it.
Cheers!
