Use this convenient dash-mount cable to easily connect your cell phone adapter cable to Digital Antenna’s PowerMax amplifiers, multi-cell phone combiners or cellular antennas. Available in 5 foot and 12 foot lengths to allow for convenient placement. The mini-UHF male end connects to our amplifier, combiner or antenna; the mini-UHF female end connects to the cell phone adapter cable. A cap protects the mini-UHF female bulkhead connector when not in use.
- All Dash-Mount Cables Feature: Our exclusive low loss, tinned braid, foil shielded, UV stable RG-8X marine cable, Factory attached mini-UHF male and mini-UHF female connectors, and Bulkhead plate and cap
- Available in 5 and 12 foot cable lengths
For the best signal transmission, coaxial cable should be located at least 3 inches away from metal. When cable is touching or very close to metal, the characteristics of the cable are altered. How much the signal is altered depends on the cables internal shielding, which consists of a braid and/or an additional foil shield. When placed near metal, a cable with 90% braid coverage and no foil shield will be altered less than a cable with 60% braid coverage and no foil shield. All Digital Antenna cable is double shielded, containing a 100% foil shield, high frequency dielectric and copper core.
When placed against metal, a 20 foot, 80% shielded cable (with no foil shielding) may change the efficiency (SWR ratio) of the cable from 1:1.05 to 1:1.2. The system will operate, but not as efficiently as it would with better cable or cable placement away from metal.
Consider all factors of the installation, including proper cable type, cable length and cable placement. Since there is no way to totally eliminate the effects of cable installed next to metal, minimize possible signal degradation by choosing a quality cable with double shielding (100% foil shielding and high braid coverage).
Any length of cable can be used as long as you take into consideration the signal attenuation (loss rated in dB) of the entire cable run. Determine your frequency and calculate the cable loss by using the cable loss chart below.
The total cable run loss from the repeater to the outside antenna should not exceed 10dB. The total cable run loss from the repeater to inside antenna should not exceed 5dB. The longer the cable run, the higher the grade of cable that should be used. Higher cable grades mean lower loss. Always minimize possible signal degradation by choosing a quality cable with 100% shielding. All Digital Antenna cable is double shielded, containing a 100% foil shield, high frequency dielectric and copper core.
