Antenna Installation Antenna* 1 Wavelength (minimum) Wavelengths: 360 MHz = 32.7" (83 cm) 512 MHz = 22.8" (58 cm) 869 MHz = 13.4" (34 cm) Stress Relief Loop Weatherproof Connections (recommended: 3M™ 23 selfbonding tape) CAUTION For continued protection against risk of fire, replace the module fuse only with the same type and rating. Surge Arrestor (optional) Coaxial Cable Statutory requirements GND Mast 105U-2 ELPRO 105U-2 Multi I/O EC: Unlicensed operation limits the radio power. High gain aerials may only be used to compensate for cable losses. Antenna installation Earth Conductor at least 5 AWG (16 mm2) Use Figure 1 as a guide for installing an antenna and attaching it to the module. * For maximum range, install above local obstructions. GND at least 11 AWG (4 mm2) Earth Stake Provide good ground connection to mast, module, and surge arrestor. If ground conditions are poor, use more than one stake.
