correct, the db4e and db8e were optimized for up to ch 51 (698 MHz top end).
While the db4 and db8 were the previous versions optimized up to ch 69.
To date, I think the only antennas you'll find optimized for 14-36, the latest spectrum,
are the DIY designs provided by holl_ands and other hobbyists.
Maybe Televees has something more recent that doesn't rely on external filtering?

I have the Filter already, I guess the proper gain on 14-36 would be what we are really after.

exactly...

Hmmm, I was looking at some CM Yagi style combo antennas and they are cutoff at 51 as well... if my calculation was correct. Still goes well beyond the current TV frequencies but still smaller than the older stuff.

The Stellar Labs 8 Bay is $92 CDN on Newark... was wondering about this one. My only consideration would be Wind Loading and keeping the arms from not going out of alignment. Was thinking about pointing one end at Detroit and the other at Toledo or Stevenson/Leamington.

Also considering the DB4e or DB8e. Price for the Stellar Labs seems pretty attractive.

The 2370 is listed at $30.

I did some testing of Stellar Labs versus Antennas Direct X element antennas. A company called Solid Signal markets the Stellar Labs as their "Extreme antenna HDB91X" It is the same antenna as the 2370. Side by side comparison Same Day within minutes of each other. Not surprisingly, the AD 91XG came out on top in the uppermost channels whereas the knock off actually did better around RF 27,28, 29 :

I may revisit this now that I have a good quality Spectrum analyzer.

Has anybody ever done a direct comparison of the Antenna direct DB8E and Channel Master 4228? the more I play with these 8 bays the more I get the feeling that the single feedpoint on the 4228 is a big advantage.

I would agree.
I have tried both of these. I did not see a big difference, but the CM has the advantage of being able to pull in Hi VHF.
Even though the AD allows the separate bays to pivot, I found the best operation is when they are in the exact same direction. Also, the AD is about 2 pounds heavier.

I remember the advice of taking off the little black covers from each CM bow to eek out a little more gain; they easily come off.
