8. Secure the service loop portion of the feedline to the antenna-mounting bracket using the tie wraps. Do not

severely bend or kink the RF feedline cable.

Note: The N type connectors are weather resistant, but should be entirely wrapped in self-

amalgamating tape to ensure a water tight seal.

Performing Lane Tuning

Lane Tuning consists of selecting the frequencies to be used on the Ports and setting the attenuation

for the Ports to control the ERP of the reader. These are configured using the web interface. It is

recommended that Kapsch Services perform lane tuning to properly configure a site. If the

integrator/operator wishes to perform the lane tuning, the following guidelines apply.

• When using multiple adjacent readers, the same FDM Port frequency should not be used on

adjacent lanes, including straddle and shoulder (recommended at least 24ft. separation

between antennas for in-line antennas, 21ft (18ft lateral) between antennas for staggered

antennas).

• When using multiple adjacent readers, TDM Ports that are configured active in the same time

should not be used on adjacent lanes, including straddle and shoulder (recommended at least

24 feet separation between antennas, 21ft (18ft lateral) between antennas for staggered

antennas).

• The TX attenuation should be adjusted to obtain capture zones nominally 8 to 12 ft. (1.83 to

2.44 m.) along direction of vehicle traffic.
