Profile: Holland Electronics Corp. is a distributor of electronic products. Our product line includes amplifiers, cables, jumpers, filters and test equipment. Our HA-201T is a low noise, high output amplifier well suited for small channel capacity CATV amplification, where slope adjustment is needed. Our The HDA-10 is an all purpose amplifier for home or small system applications. DST-5000 dark meter RF sweep system generates five carriers of 20, 55, 950, 1450, and 2150 MHz. This pre-signal testing verifies if connections are correct, if all passives and cables are passing signals, and if not, where an open or short circuit exists. The measured signal attenuation levels up to 50 separate stations can be stored in memory. A built-in RS-232 port allows the user to download this data from the meter to a remote device at the push of a single button. Our diplexer provides low loss diplexing of DBS and TV signals. It separates TV and DBS signals prior to satellite receiver input, and filters harmonics in the off-air spectrum from satellite conversion devices. The DPD2 diplexer is specifically designed for Dish Networks TM DP44 installations, allowing 2 amp passing without burning out.
