Please log in for more thread options I'm looking at splitters to use on my small aircraft which has two antennas broadcasting video data. I'm new to RF stuff, could somebody please tell me what 'power pass' means and what it causes to happen? I'm looking at splitters similar to the first two at http://www.rgsplit.com/servlet/the-Splitters-cln-Power-Pass/Categories, but if anybody knows of a lightweight option that would be great.

Please log in for more thread options Pass I believe means the devices will pass DC power to down/up stream devices. I would think, unless you're dealing with extremely low powered transmitters that something like these would be more appropriate. http://www.instockwireless.com/power_divider_2way.htm | |||||||||||||||||||||||||||||||

Is the cast aluminium casing used for shielding? if so would it be possible to remove the case and replace it with RF absorbing foam? | |||||||||||||||||||||||||||||||
