-~~NOTOC~~
-====== Station Coax and Grounding ======
-This is how VA7FI manages his coax runs into the house.  It's meant as an example to help people get started, not as the definitive authority on the subject.  [[va7fi@rbox.me |Feedback is always welcome]].
-===== Outside =====
-{{  :howto:stationcoax:outside.jpg?200}}
-On the coax side:((Click on any of the pictures to zoom in.))
-  * LMR400 is used for most antennas to the transition box.
-  * The box shown here is 9``×9"×4½", but I would probably use the next size up if I did it again: there's never enough antennas!
-  * Two pieces of flattened copper pipe are used as bus bars.
-  * The coax from the antennas connects into the [[https://www.dxengineering.com/int/search/part-type/coaxial-lightning-protectors?GroupBy=ProductName&SortBy=BestKeywordMatch&SortOrder=Ascending&keyword=coaxial%20protector |coaxial lightning protectors]] (also referred to by one of the brand names: //Polyphaser//), which are mounted on the bus bars, which are grounded.
-  * From there, RG-8X coax is used to go inside the house.
-On the grounding side:
-  * The antennas up the tree are grounded to a few ground rods and a ground plate.
-  * Those are bonded to the ground plate that connects to the transition box.
-  * That is also bonded to the utility ground of the house.
-  * And is bounded to a central grounding point inside the house.
-===== Inside =====
-{{  :howto:stationcoax:inside.jpg?400}}
-  * The RG-8X from the transition box connects to the bottom of a patch panel, and the top is labelled with which antenna is connected there.
-  * Radios connect to the top of the patch panel, and the patch cords are labelled with the radio.
-  * The patch panel is bonded to the transition box outside, and the radios are connected to the patch panel.
-The patch panel makes it very easy to swap antennas between radios without ever having to disconnect anything behind the radio itself.
