Hello Everyone,

I hope everyone is safe and healthy!  [wave]

I used to have a directional antenna that was attached to a rotor, but it only lasted 2 years cause i live in a high wind area, and attaching it to my chimney was a pain.

I then switched to a 4 bay Channel Master CM-4221HD antenna that has been performing quite well.

I'm now interested in upgrading to an 8 bay.  Any suggestions, other then the Channel Master.  I would have thought Channel Master would have come up with a new design, but they're still selling the same antenna from 2015.

I haven't installed one in several  years now, But I have put up a lot of
Channel Master 8-Bay 4228 bowtie antennas with a amp.
Amp suggestion (7777)
I like the 0064 amp, by channel master, but it is not made anymore

The 4228, along with the 7777, is a great choice
I would start at about 12 or 15 ft. checking signal as You go.

This is what I use. I like the adjustable panels for a little more beam width. https://www.newark.com/stellar-labs/30-2431/hdtv-80-mile-deep-fringe-bowtie/dp/25AC5067

I use the antennas direct db8e here.
I like the horizontal stacking (or ganging), since you wind up with one high gain main lobe,
and two smaller gain sidelobes. I use the stronger main lobe to aim at weaker distant UHF stations, while aiming the smaller lobe at the strongest local Transmitters. This helps to keep the strong local signals
from overdriving the preamp, which is necessary to pull in even more distant transmitters at the same azimuth as the local TXMTR farm.

Take a look at Page 2 of the specs which has the antenna patterns and you'll see what I mean.

They have a rather liberal lifetime warranty with stateside customer support.

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
