There are 2 ways to show a photo. You can use an image host like imgur and link to the photo or you can create a photo album on this forum (User CP or Your Profile):I will have to try to figure out how to add a picture of the antenna to send. Doesn’t seem like any of the above buttons work.
How to create a photo album for use on the Digital Forum
Pictures can be no larger than 600 pixels width x 800 pixels height and 100k in size.
It is possible that the transmitted channel 7 signal got weaker. It is also possible all your signals got a little weaker because of deterioration of the antenna, but you only noticed it because 7 is your weakest.Channel 7 is the only one that got weaker.
Does your TV have a signal strength indicator to make comparisons?
