Towers take three primary forms: Lattice (Self-Supporting) towers, Monopole towers, and Guy towers. Lattice or Self-Supporting Towers: typically three sided with a triangular base. Generally tapered from the ground up and resembles a pyramid with and approximate height of up to 400’.

A Lattice tower offers the greatest flexibility and is often used in heavy loading conditions.

Coax Connectors PAGES: 1 of 1

REV: 1

Coax Connectors - Termination points for the coaxial cable. Designed to have the same impedance as the attached cable. Types can be DIN or N, male or female. The larger interface size of the DIN connector offers mechanical and electrical performance advantages than the N-type connector. Requirements: connectors tensioned correctly with no copper visible and weatherproofed when needed. Verify alignment is straight and cross-threading has not occurred. Confirm stress or distortion on the connectors does not exist.
