Upstate NY: Near and distant channels on same heading, help with distant ones?

I have a ChannelMaster 4228 (the old version) that I installed about 13 years ago and have been enjoying local stations that are about 8 miles away, and also the distant stations that are about 68 miles away, along the same compass heading. The distant channels come in clearly about 40% of the time with low signal strength, but it has been gradually degrading, so they are almost un-watchable.

The plan is to take the antenna down and clean it up, including replacing the balun, removing oxidation from the whiskers, sanding connections, using electric grease, replacing the coax cable, sealing connections, and then re-mounting it and re-pointing it.

Path is: antenna is 30 feet up, coax to exterior grounding block, enters house to a splitter with 2 cables each to a TV. A couple distant trees I can't control, a few branches nearby that are close to the signal path.

Someone suggested an amp, but I am concerned about "overloading" the current nearby channels, which I can honestly pick up with a paperclip.

Is there a recommended solution to get the distant channels?

No idea without knowing more, which is why we put THIS read-before-posting thread at the top of this section.

https://www.avsforum.com/forum/25-hd...-1st-post.html

Go all the way through that, please. It'll save a ton of back-and-forth time.

It's always a good idea to see "read before posting" posts ...BEFORE posting.

Here's your previous thread: https://www.avsforum.com/forum/25-hd...cm-4228-a.html

I'll add a location to your title, but "upstate NY" covers a LOT of ground. Sounds as if you're near the transmitters of a particular market.

Walking the fine line between jaw-dropping and a plain ol' yawn.

Hello, thool

Your previous thread:
Cleaning a CM 4228
https://www.avsforum.com/forum/25-hd...cm-4228-a.html

The gradual degrading of the distant signals could be caused by the deterioration of the antenna or by the tree growth. If you have a desire to clean your antenna instead of replacing it, do that. If it doesn't help, replace it.

We would need to see a signal report for your location before we are able to give you advice about that.

You can do a TVFool signal report here:

If you don't have more than five posts, you can't post an active link to a signal report. Just give us the short form like this:
?option=com_wrapper&Itemid=29&q=id%3de6a46686a80de c

don't let it bother you if there is a space between the last two characters

You can do a more accurate rabbitears.info report here:
https://www.rabbitears.info/searchmap.php

If you can't post an active link, just give us the ID number of the report

If you can not measure it, you can not improve it.

It's likely any amp will overload in the situation you describe.

With the repack nearly complete, it's likely your distant stations are on adjacent channels to your local stations. This makes it impossible in many cases to receive the distant channels. There's a 33 dB limit in strength between adjacent channels for reception. The repack largely eliminates out of market reception.

I don't consider 40% reception to useful except for DXing.

I'd bet he doesn't have email notifications turn on.

I'd also bet he's in the same market as I.

Recording free OTA TV for 'time shifting' has been here since 1975. Will there be DVR's to do the same when ATSC3 obsoletes existing DVR's??
