What happens if I do not install the outside and inside antenna far enough apart?
The outside and inside antenna must be installed with the proper separation, with an exterior wall and roof structure between the antennas. A minimum of 40′ of separation (DA4000SBR) or (2′ and metal car roof) or 20′ (fiberglass boat wall) separation (DA4000MR) between the antennas, plus an exterior wall/roof structure. If you do not have the proper attenuation, more distance is required between the antennas. A fiberglass wall, i.e., a boat deck, does not equal a home or office wall. Therefore, the separation between antennas must be greater. If the antennas are not properly separated, the DA4000SBR and DA4000MR amplifier will be damaged and the warranty voided.
