Waterproofing  F Connectors & Weather Proofing 

 
The included one foot long RG-6 coaxial cable jumper is used to connect the output of the loop to 
the preamplifier. This cable uses specially designed F-connectors to eliminate moisture ingress. A 
package of coax seal and electrical tape is supplied for additional 
weatherproofing. 
 
The coax seal can be cut into strips to make it easier to wrap around 
the connectors. It is suggested that the electrical tape be used first, 
then wrap and kneed together the coax seal to provide a complete 
water resistant seal. The reason for using the electrical tape first is 
when a cable has to be removed, the coax seal can be completely 
removed and not leave sealing residue on the connector threads. 
 
 

Power Inserter 

 
The preamplifier’s output is connected to the 20 VDC output of the power inserter via the customer 
supplied lead-in RG-6 cable. If a lightning protector is used in this coaxial line, it must be capable 
of passing DC. The power inserter contains a highly filtered linear DC regulator with an internal 
self resetting fuse that provides protection from short circuits. It is designed for indoor use only. 
The wall mount transformer provides 24 VAC for the power supply. A PL-259 to type F Connector 
adapter is provided for the radios that may require it.
