91XG (14-69) vs. 4-Bay w/Reflector (7 or 14-51)?

Hi GroundUrMast,

Since you own both the 91XG and a DIY 4-bay w/reflector, I would appreciate if you could share you experience with them.

(As I say this, I get frustrated at the FCC's decision to sell spectrum out from under the tax paying public. I long for the days when UHF antenna design needed to account for more bandwidth.)

There is no anodizing or other coating on the aluminum parts, so corrosion will be a problem a bit sooner. (To be fair, the Antennacraft is not anodized either.) The electrical performance of the HD8800 has been significantly less than lesser antennas, including a crudely built DIY 4-bay w/reflector.

I'm a little disappointed, since I was hoping it would have higher gain to pull in my low-UHF channels (RF 17 to 32).

Alas, looks like I'll have to try and order a CM 3023 instead Yagi (trying to avoid 91XG since many reports says it's not good at low-UHF)... but... who knows, it may work in my situation/location...
Which of these two choices is best suited for our location?
  • M4 complete kit w/curved 1x2" welded-wire reflector (7-51 0ne-antenna solution)
  • AD 91XG + YA-1713 (7-69 stacked-antenna solution)

Thank you
