Poor signal strength in canada

[pistol]

I have had DTV for years and have had no problems but lately my signal strength on a 24" round dish has dropped substantially. I used to have over 90% and recently re-aligned my dish and re-seccured it but strength has dropped....before I break out the old ladder is there anything I should know about a new bird or something technical like that that would cause this?????
I am perplexed as to why this has happened and would like to solve it.

I'm also "doing Dave", in Atlantic Canada and I haven't noticed any signal drop with my 39" Star Choice dish of late. Good luck with it though.

I have a 24" dish and have always had 95% or more and have been able get all channels all the time. But recently the highest I get is about 88% with some transponders at 0. I have not been up on the roof but was just wondering if there is problem or something they did to change the signal.

A number of possibilities.

1) The dish is slightly out of alignment, and only receiving even or odd transponders. Check your signal meter and change the transponders to verify.

2) Your coax is bad or you have some bad connections causing periodic even or odd outages.

3) Your LNBF is bad and causing the same problems.
