Highly recommend the folks at Shively. The have been great working with us on a 25 year old 6812 3 bay antenna (how's that for service after sale?) in St Croix that was damaged during Hurricane Maria (it has survived many hurricanes), trying to keep it going until a new 4 bay can be fabricated and installed. While we are going with the 6812c, I have heard really good things about their Versa2une, especially if you ever have to change frequency as they are easily field tuned.
Speaking of installation, any recommendations on a tower crew who works in the Caribbean for our new antenna installation?
