Estimating Cable Lengths:
During the survey you will be estimating the distances between the GOLIATH antennas
(TX/ATA and Rx/ARA) and the MEU to determine what length of cables to use for each
antenna. You must also verify that distance does not exceed the maximum supported
cable lengths listed below.
Maximum supported cable lengths from the MEU
Power Source 110 foot
Tx/ATA Antennae 110 foot
Rx/ARA Antennae 135 foot
Estimate the distances using any method you prefer. Remember to allow for additional
cable length to go from the roof girders to the Goliath Hardware and enough cable length
to form minimal service loops. Two methods that have been successfully used to estimate
the distances are:
 Walking the floor using a Measuring Wheel.
 Counting Ceiling Tiles. Most stores use 2 foot by 4 foot ceiling tiles. By counting
the number of tiles between locations you can estimate distances.
Coaxial cable lengths are 25 foot, 50 foot, 85 foot and 110 foot in the installation kit. Use
the appropriate length cable for each Tx/ATA and Rx/ARA. Extra 85 foot cables are
provided in the Hot Spare Kit. The 85 foot cables can be substituted for the 110 foot
cables during the installation if the shorter cables can be used.
