Breakfast Topic: FOX 7 - KTBC Broadcasting Frequency

 

Transmit Frequency 174.0 according?to?. I assume the units are MHz (not displayed).

The primary and sub channels are multiplexed on the same frequency according?to this:?.

Thanks for playing! ;-)

Thanks Alex. That's about 16.9 inches for quarter wave. 34 inches for 1/2 wave. No wonder my little 4" antenna doesn't receive KTBC very well. I'll try building a simple wire Moxon.
 

The bandwidth of Television channels is 6MHz wide, so 174-18? MHZ.
Using the formula 28?8/freq.=1/2 wave at center frequency of 177MHZ=.15.8644?6779661?2"? for 1/4 wave, double that for 1/2 wave.

You should really make it a folded dipole for 3?? Ohms, then use 3?? Ohm twin lead to the TV, and a the good old 4:1 balun at the receiver.
This is old school, but this is best for low loss, and noise rejection.

It's amazing what telescoping rabbit ears can do!
