This is a great basic antenna for your low power FM transmitter. The LPFM J-Pole is vertically polarized with about 3dbi (2.5 dbd) of gain. The average height is about 95 inches but varies slightly with the frequency it is tuned to. The antenna comes in two pieces with a screw connector in the middle for easy transport and storage. This antenna will handle at least 250 watts of RF power. This antenna has an SO-239 connector on it which mates to a PL-259 connector. These are the standard style UHF connectors. Please contact me if you radio system uses a different style connector, as you may require an adapter.
I did some price comparisons online and this is definitely the best priced Low Power FM broadcast antenna I have found. similar antennas cost $150 or more and have the same level of performance as this one. If you are looking for an affordable antenna for your neighborhood radio station, special broadcast station, or Christmas holiday lights display, look no further.
Each antenna is custom built and tuned to your particular broadcast frequency. You also will have up to 4Mhz of bandwidth if you need to wiggle up or down in frequency a bit. When you order this antenna, please leave a note during the checkout process to tell me which transmit frequency you want it tuned to, as each antenna is custom tuned when built. Not sure on what frequency to use? You can search for a vacant FM channel here.
The performance of your antenna is awesome. I actually had to turn the volume down on my headphones, did not have any dead spots and the sound was much crisper than with my old antenna (wire inside PVC pipe). And, I only stuck it in the ground so it was not elevated above roof tops.
