For some stations on the 100kwatts site, there are multiple transmitters listed for a station. For example in Buffalo on WGRZ-DT ch33 at this link http://100kwatts.tmi.net/tv/BUF.html there are three different transmitter powers on the same tower. What are these three different listings. I can't find this documented on their site. Any suggestions.

May I piggyback a question on yours since you ask about the same site I had a question about.
http://100kwatts.tmi.net/tv/TKA.html


take a look at the bottom of the page. KTKA is at 3470kW DA What the heck is DA?? I get channel 13 WIBW much better at 316kW than KTKA. Is that becuause of KTKA being a much higher frequency and UHF???

Answers to the questions:

WGRZ-The first transmitter listed is a temporary low power transmitter(STA). The FCC is allowing DTV stations to serve their city of license with these low power stations until a permanent DTV transmitter is completed.

The second one listed(CP) is a construction permit for a transmitter authorized by the FCC. The last one listed (app) is an application the station has made to the FCC to modify their transmitter.

KTKA- DA means Directional Antenna. Judging from the transmitter location KTKA is likely sending more signal E/NE and less W/SW.


Hope this Helps.

Thanks Charles, that makes sense since their market is east and northeast of their tower.

The higher the frequency, the higher the power required to achieve the same coverage.


The maximum power allowed for analog transmitters is as follows,


Channel 2-6, 100Kw

Channel 7-13, 316Kw

Channel 14-69, 5000Kw


For digital transmitters in the UHF band, the maximum is 1000Kw.
