The team is upgrading the feed lines and patch bay at the N2MO station.  First off, I admit we stole the idea from K7ZSD.  Link: http://www.k7zsd.com/patch_panel_assy.htm

This is the cable from the operating positions to the patch bay:


Cable is 1/2 heliax, with N and 7/16 DIN connectors.   Lightning protection is Alpha-Delta with 7/16 DIN connectors, located in the attic at the entry panel.  

The cable from the patch bay to the lightning protectors will be routed on top of the gray brackets using Andrew L4Click hangers on the studs sticking up from the wall brackets.

Martin, that is some BEAUTIFUL work there.  Neat, organized, well executed.  Makes me feel a little guilty about the rats' nest of wire and cable behind my rig.  Smiley

Ken,
Appreciate the complement.

N2MO is a working  exhibit at the InfoAge museum in Wall Township, NJ.  We are trying to present the hobby in the best possible light to the public, including quality of work.

There is more information about the N2MO station on the website at: http://www.n2mo.org on the "N2MO Station at InfoAge" tab

Photo of Jeff,  N2LXM assembling the protector frame.   It is attached (via insulators) to a pair of 2x6 that span the rafters and joists:  http://www.sarex.us/temp_pix/Ground_strap 001.jpg

Protector frame partially installed:  http://www.sarex.us/temp_pix/Ground_strap 005.jpg  The bottom bracket and insulators were installed afterward

Did a home version of that a few years back.  I used bulkhead UHF and N connectors.  You can see it here:

Excellent work!  Have you had any problems with center pins loosening up with repeated connect/disconnect cycles?

Adding a couple more pictures of the install for those interested:

Patch Bay showing rack-mounted triplexer and 5KW dummy load: http://www.sarex.us/temp_pix/thumb_9116_18_012.jpg

Trapeze for mounting protectors: http://www.sarex.us/temp_pix/thumb_9116_18_011.jpg

Unistrut hangers for the heliax in the attic.   The heliax is held in by Andrew hangers: http://www.sarex.us/temp_pix/thumb_9116_18_014.jpg

Side project:    Clock display in Radio Room One.  There are duplicates in Radio Room Two and the classroom.  All are tied to the building master clock via an IP connection: http://www.sarex.us/temp_pix/thumb_9116_18_013.jpg

Doesn't have a lot of cycles.  So no loosening as of yet.  It's been installed for about 5 years and since I only need to pull one end to disconnect for lightning, I switch off.  The amount of time I switch between radios is small, but since I run hardline from the rotor loop or antenna to the back of the panel, I needed a way to transition the cables somehow.  This worked best.

I've been thinking about doing something like that here at the QTH. Do you have a link to the clock you use?

Ouch!

Actually, not a bad price, but more than I should pay...

The heliax between the patch bay and the protector frame in the attic has not been installed.

More Progress:  Installing the FSJ2-50A  feedlines from the patch bay to the lighting protectors in the attic.   There are seven more of the FSJ2-50A heliax, and multiple rotator cables going in next weekend.



Shows the 14 cables to the operating positions, triplexer,  and 5KW dummy load.
