“So we did a test broadcast today of a church service with only the pastor and one reader and a woman with a guitar. And it was terrific - the speech quality was excellent…and the sound quality of the music was very good as well. All in all, it was a complete success... thanks very much for helping to make this happen!”

“I want to thank you for this helpful product. We ordered the transmitter for our church services. I was unaware that low-power AM transmitters were allowed under FCC Part 15. It worked like a charm.”
Gary Adams, Pastor
Kelham Baptist Church, Oklahoma City, OK

"Works really well. Used for outdoor church service because of covid pandemic. Transmitter was installed and hooked into sound board inside church with only the included antenna hooked up, also inside church. The signal was broadcasted all the way around the (decent sized) church. Clear signal in every car. Was used with music and speaking. Sound quality wasn't perfect but it was better than I expected it to be considering it's an AM transmitter. Definitely worth the money."

“I like the see through glass on the Range Extender. I can easily look up and check the peak from the ground. I want to purchase another one very soon, as I am pleased with this one. I will talk to some other churches and ministries about installing a radio station.”

“Works really good. Much stronger signal and will do what Church needs it to do and then some. I may purchase another exact setup, for me, in the near future. I really like the design and construction of the antenna/tuner!”

Frequently Asked Questions
How can the InfOspot Transmitter operate without a license? The InfOspot TH.5 Transmitter is FCC-certified (ID #DLB5LTT98) and approved for broadcasting under Part 15.219 of FCC rules, which allow unlicensed operation of a certified 100mw AM transmitter without a license as long as the antenna + ground does not exceed 3 meters. See: 15.219 - Operation in the band 510-1705 kHz.
 
When I connect my InfOspot Transmitter to the Range Extender Outdoor Antenna and Tuner, is the coaxial cable between them considered part of the ground lead? It is not. The FCC certified the InfOspot Transmitter for operation with the interconnecting coaxial cable to its Outdoor Antenna and Tuner as a complete system. Any length of coaxial cable may connect the Transmitter with the Antenna and Tuner, because the cable itself is not part of the antenna system. The InfOspot Transmitter is also certified to operate on its own with a 3-meter wire (indoor) antenna.
 
Why haven't you come out with a FM version of the InfOspot System? The FCC rules for unlicensed FM broadcasting under FCC Part 15 limit the range of FM systems to just a few feet. But under the corresponding AM rules, you can produce a ¼ to ½ mile signal. That is partly because the FM rules include a signal intensity limitation that keeps the signals contained within100 feet. To make matters worse, due to the much shorter wavelength, FM signals are more easily blocked and fade more quickly. In addition, the FM band is much more congested than the AM band, making an unused / quiet FM channel very difficult to find.
