[K3CAL] Hospital Installation

[Shawn Donley]

Chuck,

Had considered 1/2 inch like LDF4-50A but not sure if there's enough on the roll CARA owns to do the hospital and have enough left for other projects (which are on hold, like new coax for Prince Frederick).  But we could purchase LDF4-50A from TheRFConnection for about $2.00 a foot.  Not sure we would need it for the 440 link too, considering you can see the Mt Hope towers from the hospital roof (8 mile line-of-sight).

But if you have connectors to donate for the LDF4-50A, that would swing the economics in favor of using it.  

Also a bit concerned about how much space is left in the room entrance boot.  Picture attached.  That's one reason I listed 1/4" Superflex in the "alternate item" summary of the spreadsheet....smaller diameter.

Both the roof and the equipment room can be reached by elevator and one flight of stairs ... no expensive tower climbers needed.  We will be moving the 2M repeater to the hospital as an experiment once the antenna and coax is installed.
