VERIPOS recommend and supply pre-terminated LMR coaxial cables as they give the

best performance in permanent installations. Label each cable carefully at top and

bottom identifying the antenna attached.

3.4.1

This cable is recommended for the main cable run to the antenna. The main run should

be a single cable, joins are not recommended. If possible, measure the cable run and

order a pre-terminated cable. These have proved to be more reliable in service.

The use of LMR-400-DB (direct burial) cable is recommended as this contains a water-

block, which will prevent water from contaminating the whole cable if the casing is

accidentally cut.

See the Reference information chapter for detailed specifications of the Times LMR 400

coaxial cable.

3.4.2

This cable is recommended for use in short runs and is the cable used for the pre-

terminated tail used between the main cable run and the antennas or below decks

equipment.

See the Reference information chapter for detailed specifications of the Times LMR 240

coaxial cable.

3.4.3

The signals received by the antennas will deteriorate at different rates as they are

transmitted through coaxial cable. As a result VERIPOS recommend a maximum cable

length.

The following table details the maximum length for each signal type.

RG213

LMR400

LDF4-50

Longer cable runs may be achievable with the use of in-line amplifiers. Contact VERIPOS for

guidance.
