We will be off the air for a few hours as we move the current antenna back to side mount. We seperate the transmission line somewhere close to this new location and run it over to the side mounted antenna location. We are back on air on channel 21.
Then we do all the work to mount the new 25 antenna on the tower top. We will have to lower power as the worker pass by, but we should remain on the air during most of the modifications.
We install a different transmitter and modify it for channel 25 while all the tower mods are done (we will not modify our current channel 21 transmitter. It doesn't have enough power). Once finished with that, we connect it into the transmission line and put the transmission line back together at the tower side mount location to feed the new antenna (after testing it, of course). So we will be off the air for a few hours again.
Now we own a nice channel 21 transmitter and antenna which are useless. Anyone want to buy a 7,000 Watt channel 21 digital transmitter? It's solid state!
The new transmitter uses an IOT (tube).
