I'd appreciate a reply from anyone who has disassembled a Channel Master 4228 on how to do it and whether the results are acceptable. I plan to put a 4228 in my attic and the only entry point is about 35" diagonally.

Anticipating a few comments:
I do understand that outside is preferable.
I'm specifically looking for a CM4228 because I need exactly one VHF station on Channel 10.
I understand that there is an updated 4228 in the works (lighter, with a solid screen).

Hi there

I installed my 4228 in the attic by drilling out 4 aluminum rivets holding one side of the reflector. Reassembled with machine screws and nuts (the nylon-locking type). Others have written that there's no need to remove the rivets; just use pilers to un-bend the tabs holding the screen.

Regards

^ as was suggested - just straighten the tabs holding the screen and bend them back for reassembly.

The preformance on the VHF band peaks around channel 10.
The 'new and improved' version doesn't appear to be. It is a cheaper design from China. CM has closed their US plant a week ago. :mad:

Why won't/can't you put it outdoors? :(

Why won't/can't you put it outdoors? :(The NBC station covering Lansing couldn't get a decent post-transition UHF slot and pretty much had to take their VHF station. Fortunately, that is channel 10. (So, if you want post-transition OTA in the Lansing area, you need to pull in UHF and channel 10. Sounds like a CM4228.)

That's good to know about the "new" CM4228; thanks. Everything I'd heard to date sounded optimistic and focused on the lighter weight and continuous back screen. I'm no expert, but I understood the guess to have been that the new CM4228 would be less demanding than the heavy CM4228 at the top of a mast and also a reasonable performer right across VHF-Hi.)

On the attic mount - it's not that I can't mount it outside, it's just not necessary for us. We get perfectly good reception with a Silver Sensor, so I'm just planning to put in the attic antenna for aesthetics. (I may eventually put a directional antenna up on the roof to try to get a signal on channel 19 that's just outside our LOS.

Thanks to all for your replies.

I have not idea what rivets people are drilling out and why they would do such a thing. I just took some needle nose pliers and released the clips, brought it though the attic access (just barely fit) and then clipped it back togther. Mine is mounted on a 5' mast and pulls in stations 60 miles away. I get channel 4 watchable, 5, 7 and 9 analog stations on it. I don't watch them because I only watch digital stations and they are all on UHF.

I too have looked at the new CM4228 but it is 49" wide and this one is big enough.

Hi there

There's no need to confess your inadequacies.
Since the sale price of one 4228 was less than two 4-bays, there was an initial plan of breaking up the 4228 into two separate antennas.
