3.6.2 IALA beacon antenna and cable mounting
The construction of the mount enables routing of the cable either along the inside or the
outside of the mast tube. A more detailed mounting specification of the IALA Beacon antenna
is found in Appendix A.
An RG-213 or RG-214 cable is used for distances shorter than 50 meters, a ½" superflexible
cable is used for distances longer than 50 meters.
Install the antenna as follows:
1. Attach the antenna to a mast tube or pole by using the provided U-bolts.
2. Attach the antenna cable to the antenna.
3. Wrap outdoor cable connections with waterproof self-vulcanising tape as described in
section 3.5. An alternate way of waterproofing is to use heat shrink hose with glue. The
hose should cover the whole connector and part of the cable.
4. Make sure the ground strap at the antenna base is connected to a suitable place ensuring
good grounding. When installed, the terminals of the ground strap should be sealed from
moisture to prevent corrosion. Paint or silicone sealant can be recommended for this.
5. Secure the cable to the mast every one to three meters with clamps or bands.
6. Route the connector at the other end of the antenna cable to the main unit. Connect the
cable to the DPS 200 unit. A short RG-213 or RG-214 cable is often needed in order to
secure cable runs into the cabinet. This cable is included in the DPS 200 package.
If the antenna cable is attached to the DPS 200 unit, do not attach the antenna cable to
the antenna when the unit is running. If the antenna cable is short-circuited with
POWER ON, the IALA Beacon receiver will be damaged.
