300 kW. From 142 kW (on a higher channel).What the article doesn't say is what they are increasing their power to?
It's not a technical blog post, as far as I can tell, and so is vague since the presumed audience wouldn't understand it anyway. But their old antenna was a mid-power model running at 142 kW ERP. The new one is a high-power model at 300 kW ERP.It also doesn't explain why a more powerful signal requires a "larger antenna".
Not sure why the OP thinks 300 kW is such a big deal. Sure, it's double the power they had before, but almost all the other major networks in St. Louis are 1000 kW, or close to it, so KETC is behind the curve in that regard.As noted in the other thread, I moved a collection of non-ATSC 3.0 posts to this thread.

If they also dropped down in RF frequency, the ability to cover more ground comes with that.I said “doubled their power.” Which they did, no?
Actually, the article uses the phrase "one or more".On edit: Wikipedia seems to say one subchannel must go.
I get Charlotte OTA and trust me it is the latter. It is dreadful. I can’t understand how you as a company elect to participate in the auction knowing what the outcome is going to be and then complain about the problems it brings you. This just proves some care zero about OTA viewers and quality.Woof!
Two 720 and six SD. Must be some pretty awesome multiplexing hardware (or a really awful viewing experience).
I suspect that it is a combination of things:This just proves some care zero about OTA viewers and quality.
Good point, other than the PDX signals going N/S where there is less altitude. I live South of Astoria, along the coast and the days of getting PDX or SEA OTA directly are gone. Even it I detect a signal from SEA, like (14), never strong enough to lock. All I get now are the 5 live translators and sub channels from 2-6-8-10-12 PDX. 3.0 may make a difference. I used to get both PDX and SEA in analog, but not strong. Of course those were the VHF days.The Portland market is probably a poor example as it covers a lot of territory with a significant number of translators. The market is perhaps 250 miles across at its widest point and covers southwest Washington and a small oddly-placed part of Idaho.
Due to two mountain ranges (Cascade Range and Coast Range), more power out of the Portland-area towers gets you mostly just a higher electricity bill.
I'm thinking of the more common situation where stations are packed in much tighter or where one market has most of the frequencies tied up (like NYC or the SoCal situation).
The move towards directional arrays surely isn't going to be appreciated by those who prefer OOM TV stations to their own.
