Weather Proofing Coax Connections
1. Lightly coat the threads of the connectors with silicone lubricant prior to assembly (See Note 1) and hand tighten. Make sure
to use the silicon sparingly so when assembled, any excess does not get on center conductor. Care should be taken not to
get any lubricant on the center conductor.
2. Wrap the connector assembly with a non-adhesive silicone tape, EST part number AA243, for weather proofing (See Note 2
and instructions below).
a) Clean surface to be wrapped. Cut off length to be used.
b) Peel back a short length of protective film. Keep tape clean and dry.
c) Begin with one complete overlap of tape onto itself.
d) STRETCH CoaxWrap while continuing to wrap object with “half-laps”, removing clear film as you go (Figure 1). For
greater pressure resistance, use 2 or more tightly wrapped layers.
e) End of tape at final wrap should be completely positioned onto itself.

Note: CoaxW
rap’s bond begins to cure immediately upon contact with itself. Repositioning or
removal is not recommended after 2 minutes of wrapping.
Figure 1: Installation Example
3.
Apply an electrical coating (sealing agent), over the vapor barrier patch for added
protection (See Note 3).
NOTES:
1. Dow Corning RTV-3140 or equivalent.
2. CoaxWrap, CW10B or equivalent.
3. SCOTCHKOTE, 3-M Company, or equivalent.
Grounding
All building mount antennas require attachment to a good earth ground for optimum efficiency. Contact a reputable local
communications shop for procedures for your area.
Lightning Arrestors
Lightning arrestors should be used on all external building mount antennas for personal protection and to minimize damage to the
transceiver during lightning storms. The units should be installed as per manufacturers instructions provided with the device.
Enabling Transmitter for SWR Testing
The ESTeem 195C and 195M are packet burst wireless modems, so measurement of the forward and reflected power during
operation is difficult. To enable the transmitter for measurement with a directional wattmeter, enter the following software
command:
