SP-1300 Combiner/Splitter

[dwayne0564]

Hello,

Anyone use one of these splitters, would be running it on about 75 feet with a tram discone, just wonder about signal loss,

Thanks

By its very nature, there will be a 3db drop (1/2) in output. That's usually of no concern but a discone, also by its nature, offers no gain; although, over a back of the scanner antenna it would provide better reception just because it's outside and higher.

Signal strength improvement depends upon the antenna, coax and any adapters such as splitters/combiners, anything you add into the coax feedline. Start with some decent coax designed to play well at the frequencies you want to receive, and keep your coax run as short as possible. A gain antenna would help but that’s not what you are running? Not necessarily a problem… as previously stated, just getting your antenna outside and up as high as you can should do. I run a 50 foot length of LMR400 for coax and noticed a difference at the 400 and 800 MHz frequencies. RG58 is great for CB and VHF Low Band 30-50 MHz, squeaks by at VHF High Band, but not with the higher frequencies. LMR400 is not the only choice as it’s thicker and less flexible but a short run of more flexible coax is ok to add to it and connect to the radio.

Sorry my reply doesn’t fit your concern exactly, I just get a little paranoid when I see anything that may adversely affect signal strength. I have no experience with that splitter.
