The only problem I had with installing the base was the spacing of the holes already in the roof of my Winnebago Brave. When replacing the existing antenna I had to modify the mounting plate to accommodate the coaxial cable from the antenna to the signal director inside the coach. The second hole for the coax made it a little difficult to place and seal the base plate. After trimming the base plate I was able to secure it to the roof with screws and sealant. No leaks so far.

King Mounting Plate makes for a “King” install
If you are retrofitting the King Antenna on a motorhome, this mounting plate makes sense.The original system had the coax coming through the roof about a foot away from the old antenna. This mounting plate covered that hole, and provided a good base to mount the King Antenna to. Highly recommended.

It helps
Made the installation simple, four stars because it wasn’t absolutely necessary, just makes covering existing holes when replacing old antenna easy.

Mounting hardware not included
The tag on the plastic envelope containing the plate states stainless steel nuts and bolts are included to mount plate to antenna. No nuts and screws were included. UTUBE demonstrators and product reviewers have stated plate came with mounting hardware. I want seller to send me mounting hardware or I will return for refund and purchase elsewhere. If I receive mounting hardware in a timely fashion I will change from two stars to five and upgrade Easy to Install from one star to five.

Base is a little small
It is a little small to cover the old antenna mount, but I was able to make it work
