Evertz RF distribution products split, combine and amplify L-band, 70/140 MHz IF and off-air signals from 40 MHz to 3 GHz. Passive 7702SP cards and SRF rack arrays need no power; 7702/7703DA and 7803DA active splitters add low-noise gain, slope compensation and up to 16 isolated outputs; and the 7703PA amplifies and slope-corrects weak or long-cable L-band feeds. Most are hot-swappable cards for Evertz 7800FR and 7801FR frames, with LNB power pass-through options.
Key features

Frequently asked questions
Passive or active splitter?
Passive splitters lose about 3 dB per 1x2 split but need no power; active splitters make up that loss and add slope compensation and monitoring. For more than four outputs or long cables, an active splitter is usually the better choice.
