Extending Antenna Range
In areas of high radio frequency (RF) interference, the intercom may not work
as a wireless system. In these areas the keypad antenna will need to be extended
(run closer to the house) using RG59 or RG6 co-axial cable, which is the same
type of cable used for cable TV.
You will need enough co-ax cable to run from the keypad location to a conve-
nient location close to the house, but not closer than 10 feet from the intercom
base unit. You will also need two F-connectors for each end of the co-ax cable
and a F-connector female adapter to connect the antenna from
the keypad to the end of the co-ax cable near the house. The
co-ax cable and connectors can be found at hardware and
electronics stores.
Run the co-ax cable in PVC conduit from the keypad at the gate to a convenient location at the house. A typical location
might be on the side of the house by the garage. Attach a F-connector to each end of the co-ax cable. Remove the antenna
from the keypad and connect the co-ax cable to the keypad as shown in the diagram above.
Connect the antenna to
the other end on the co-ax
cable using the F-connec-
tor female adapter and the
F-connector and mount the
antenna to the side of the
house. The type of mount-
ing hardware will depend
on the type of siding on the
house. Mount the antenna at
least four (4) feet above the
ground. See example to the
right.
IMPORTANT:
DO NOT
run co-ax cable in same
conduit with AC power or
with-in 3 feet of AC power
source. DO NOT mount
the antenna to any metal
buildings or metal post.
Antenna from keypad
mounted close to the
house but not closer
than 10 feet from the
base station.
