Assembling the Antenna to the Ring
(2.4m &2.7m)
The mount should be assembled at this point. Now it is time to install the antenna.
Locate the 1/8” pilot hole; one is located next to one of the six, 5 / 8 ” holes in the 2.4M/
2.7M dish and the other is found on one of the 6 tabs on the mount next to the 5 / 8 ”
holes. (NOTE: These holes
do not
line up with one another, they are only to identify the
alignment of the dish to the mount.) Place the ring in a vertical position. (see fig. #1)
Bring the dish vertically to the ring. Align the pilot holes. Insert a ½” bolt, metal washer,
rubber washer into the ½” holes in from the front of the dish. You will use every other
hole at this point, which will be 3 holes.
Behind the dish you must insert a rubber washer
between the dish and the ring tab.
Secure the bolt with a lock washer followed with a ½”
nut (loosely tighten). Next install the feed struts. The feed struts will be installed in the
remaining 3 holes. Use this sequence: bolt, metal washer, feed strut, rubber washer. On
the backside of the dish, insert a rubber washer between the dish and the ring tab,
followed by a lock washer and a nut.
Please do not tighten nuts at this point
. Next
install the feed collar (C 13F collar) unto the feed struts. Secure with 6- ¼”x 1 ½” bolts
and ¼” locknuts. See photo group #1. Your next step is to tighten the six bolts that
secure the dish to the ring.
DO NOT OVER TIGHTEN.
This is also
addressed in Preparing the Feed Assembly.
This photo is simply showing the mount in vertical
position after we have accepted the antenna to the
mounting ring. Feed struts are installed after the
antenna has been bolted to the ring. Please note
that the 2.4m & 2.7m only have 3 struts while the
3.0m will be using 4 struts with the 48” ring as
shown.
