Hope you're wrong but I'm afraid you're right!
I use Ayrstone on my farm and it will reach 500' without a problem. It will allow the signal in surrounding buildings as long as they are not metal. Give them a call I've had great luck with their service for years.

I'd also like to know what lens and which pics were taken with A7III?
Just hard to beat the clock!
Thanks for my morning laugh! First thing I do every am is to look for your post!
Didn't see Jackson in the first one. Don't tell me they took him down too!
