The biggest wall mount bracket I've seen is 18". Google CM9036.

You could use an Eave Mount such as the Channel Master CM 9030 Adjustable Eave Mount (CM9030) or the Ronard 730 Heavy-duty Under Eave Mount (730). I don't know if either of these would be strong enough for a 4228 though.

I dont think you will find any premade brackets that extends out that far.

Your eves is 3'.

Most wall mounts that clear the eves use a 12 or 18".

You may have to go get some custom ones made.

Draw up some simple plans on graph paper with accurate measurements/angles and take it to a local metal shop. They'll be happy to do the work for you.

hi there,

I'm struggling to find the best way to mount an outdoor antenna to the wall of my house. I really don't want to mount it on the roof.

Question:

Can I Mount a "J-Mount" (ie. the mount used in satellites) to the wall, and then insert either a mast or a 4228 ?

In otherwords, I want to use the j-mount to hold the mast in place. Then if necessary add sections of mast for height, and for support purchase "V" brackets for support against the wall.

Part of my problem is that i need clearance to get by my eaves (roof-overhang).

I'm simply looking for the easiest way to mount a 4228 to the wall and clear the eaves.

Thanks in advance,
Allen

Hi Allen, this thread has lots of previous posts on mount options, including the one you mentioned in post #112. I know from personal experience that a properly fastened and tightened J-Mount will hold up a CM4228 on a 5 foot pole with no problems. I would not go much higher or heavier than that. My only concern is that you might get multipath issues from having it so close to the house structure. If you have aluminum siding like my place does you aren't going to be happy...

Earlier in this thread, stampeder linked us to photos of failed towers. (post #76)

From that same site, some easy reading on antenna towers for your home.http://www. tvantenna.com/support/tutorials/towers.html

stampeder · 2006-11-20, 03:40 AM

That's correct, timbo, and everyone should keep in mind that what they call the Taco DMX line of towers in that web page is actually the same thing as the Delhi DMX line which you can see from the Wade website:

I have a 4228 and it looks like the best spot to mount it is to the chimney. We actually just had it repointed and rebricked, so I need to find out how to mount it using the least amount of drilling holes in the bricks.

Any suggestions?

thanks

Use a chimney mount -- it wraps around the chimney.

The old Radio Shack model is 15839. The Source uses the same part numbers.

stampeder · 2006-11-23, 07:54 PM

Also see the photos in the Pimp My Gear thread - there are several pics showing chimney mounts.

byebye rogers · 2006-11-25, 01:47 PM

Thanks guys I'm going to the source today and I'll check the pics too.

I have looked through the forum's threads but have not found anything that addresses my specific question. I'm in Indianapolis, IN and live approximately 20 km from a few VHF and UHF broacasters and 70 km from other UHF broacasters. I have been looking into DTV OTA reception and the antennas used for it for about a month now. Here is my question:

Can I combine a VHF/FM/UHF antenna (like a CM5646) pointed in one direction and a UHF only antenna (like a CM4221) pointed in another direction or will UHF signals received by the combo antenna cause conflict with the UHF signals received by the UHF only antenna? Another way to put it is:
Can you use a combo antenna (VHF/FM/UHF) with a UHF only on the same OTA antenna system or do I need to get a VHF/FM only and a UHF only for my system? The reason I want to try to use a combo is that I have VHF/UHF broadcasters in one direction and UHF broadcasters in another direction and don't really want to get 2 UHF only antennas and 1 VHF only antenna if I can help it.

No this will not work.

A signal will arrive at the front of 1 antenna before it reaches the back of the other. This will lead to multipath on some or all signals.

Compared to using 1 antenna:
1) some channels will be watchable
2) some will be cancelled out
3) some will be subject to freezing and/or pixelization.

The answer is to use 1 antenna with a rotator

Brewmaser · 2006-12-05, 05:54 PM

It seems some people can get this setup to work, but I blew my brains out for a month before breaking down and buying a rotor.
