Tru-Match FM Broadcast Antenna

We’ve been besieged with calls asking us where to get a good quality FM Broadcast antenna. Well, we put one of our best RF engineers to the task and came up with this killer of an antenna, we call it the Tru-Match 100. Why Tru-Match? Because matching your antenna to your transmitter is the single most important link in your transmitter set-up - and a good antenna and match is the secret to getting maximum range. When we say match we mean electrical impedance match... if the proper impedances are not maintained between transmitter and antenna, power is reflected back away from the antenna and back into the transmitter! This can cause the final amplifier stage to be damaged, not to mention a spurious signal and lousy range. In real commercial transmitter installations, it is not uncommon for the antenna matching equipment to actually be larger in size than the whole transmitter itself! Our antenna kit consists of rugged pre-cut PVC pipe, antenna radiating elements and of course the proper matching assembly and is fully water-resistant when assembled. The antenna is easily mounted to any standard TV antenna mast like you can find at Radio Shack or K-Mart. A standard ‘F’ style coax connector is used, so that readily available, low cost RG-59 TV coaxial cable can be used for connection. And we even supply an RCA phono to F Male adapter for easy connection to any transmitter antenna jack. Total length of the antenna is about five feet, and it is easily mounted horizontally or vertically polarized - yes, we even explain in the manual the pluses and minuses for each. Maximum input power is now 25 watts. If you’re serious, and want a good signal, the TM-100 antenna is for you. You can put this antenna together in less than an evening
