The Gates Air Flexiva 1

We just finished installing one of these units for one of our clients. This is the third one that I have dealt with in the last two years. I have to say, these transmitters are pretty cool.

We also installed a 7/8 transfer switch and a 1.5 KW test load:

Rarely, if ever, have I worked with 7/8 rigid transmission line. Usually, it is 1 5/8 or 3 inch line, which require some amount of patience when installing.

Nice little transmitter site upgrade project.

    Thanks for the up to date photos on Illinois Mtn.!
    I remember the day that WPDH Continental went to air in about 1982,
    it was by far the best and only dependable FM transmitter in the market!

    Question;what’s in the old WFTI/WTBY-TV room these days?
    I suspect that 2 ton UHF antenna and waveguide( stainless steel rectangular transmission line) will be on that tower forever…

    Love those PIRA RDS encoders! I generally don’t like cheaping out on things but these have features of units costing 5X as much and the only thing they lacke is a metal case and internal PSU, which if you really need to can be added (DIY) for under $100. Still a great value! spend the extra $1,000 you save on a better remote control or processor….
