[W2CRA] CRA Tech: A New Opportunity!

[Kurt Cathcart, KR2C]

I'm looking for 2 to 3 people to assist with this project.


I figure we can carve this out into two efforts.

1. Lower existing mast

     a. safely lower mast keeping the mast from bending and preserving 
the weather station

     b. remove weather station and associated cables

     c. mount new 220 antenna to mast

     d. attach coax to antenna and secure down mast to the roof line.

     e.  restore mast/antenna to vertical.

2. Coax run

     a. remove existing coax from feed-thru  preserving the existing 
connector.

     b. run new coax around building maintaining a 6" minimum radius bend.

     c. secure coax to building using P-clamps and masonry screws.

     d. pass new coax through entry point vacated by old coax.


I don't have a means to move a ladder so I'm hoping somebody can assist.

I'd like to do this on Saturday morning starting between 8 and 9.  
Please respond if you can assist.
