The SP - 3 is a specially designed two way antenna splitter/combiner for VHF-UHF receivers, such as scanners. The SP - 3 allows two scanners to be connected to one antenna, but unlike cheap "TV" splitters, this splitter ensures there is NO interaction between the scanners. If one output is open or short-circuited, the signal level to the other scanner varies not more than 1 dB. This ensures that each scanner can be tuned to any frequency in the VHF or UHF bands if it is connected to its own antenna. The high isolation of the SP - 3 prevents scan stops due to oscillator radiation from the other scanner and prevents also signal loss when one scanner is tuned to the VHF band and the other to the UHF band. Like the SP - 1 for shortwave, the SP - 3 can also be used as combiner. This allows the use of two different antennas (for instance a log-per and a discone, or separate VHF and UHF antennas) on one scanner without mutual interaction problems and switching.
