The cut off frequency for 7/8 heliax is so low that the 5.8ghz wave can not operate on the large of a cable.
You should have got 5/8 Heliax as it is the largest coax you can use and still pass 5.8ghz. Here is the spec sheet for the 5/8 http://www.midland.ru/products/andrew/pdf/LDF45.pdf Kurt Fankhauser WAVELINC P.O.

In the process we lowered the ODU 150' for accessibility issues (this is a difficult tower to climb). So we have dish still in the same place, but trying to 7/8" Heliax between the dish and the unit. No Link. Using the "Spectrum Analyzer" function on the GUI, we see no signs of life anywhere. Could this be a 7/8" Heliax issue, or DOA?
