Install guidelines
Besides the antenna itself, parts include mounting options for an install that is accessible by
crawl space or one that is not. Optimally, It should be located central to where signal is
needed with minimal obstacles. The range of this antenna is dependent on three factors:
1. Physical obstructions
2. Power generated by booster
3. Signal level received by the outdoor antenna

Installation
If accessible by crawl space:
1. Drill a center-hole. The size should be large enough to allow the antenna’s threaded
plastic cable base to pass through.
2. Assemble the antenna as shown in the illustration with foam ring
and metal mounting plate (with interlocking pegs facing down).
3. Push antenna to ceiling surface with antenna cable
passing through ceiling.
4. From crawl space, use the threaded fixing
nut to secure antenna by tightening
around the threaded plastic cable base.
5. Connect female antenna connector with
low-loss cabling.

2. Use metal mounting plate to align, mark and drill 3 holes into ceiling surface and insert
provided anchors.
3. Secure metal mountings plate to ceiling by inserting provided screws through mounting
plate (with interlocking pegs facing down) and into ceiling anchors.
4. Place foam ring onto antenna as shown in illustration B.
5. Push antenna to bracket surface allowing cable to pass through ceiling hole. Align
keyhole mounts on the antenna with down-facing pegs and twist into place.
6. Connect female antenna connector with low-loss cabling.
