Love the organization of the cables and the build out. You put a lot of thought into this and it shows. Well done !
Thanks Ham Radio Basics for stopping by and watching....more to come on the organization.
Looks good, well organized for future expansion. I was wondering if you could daisy chain the switches. Don't recall what coax you are using ? Are you making your own cables? Really like the new connectors from Messi! Also, I'm thinking of setting my shack up permanently off of solar power and battery backups. If this is done, you would not want to bond to the existing house ground for fear of a double ground loop, if I'm correct? One more thing. You didn't go into detail on the MFJ Relay and SDR box installed behind your rig in the corner? Good stuff here !!!
The MFJ and SDR are not hooked up yet...very observant. Once I get them hooked up and working, they will have a their own dedicated video.
Nice setup. I always enjoy your videos for hams with limited space.
Thanks for watching and the feedback RedStickHam.
I too have the Chameleon F-Loop, i have the attic as well. But unfortunately i have a metal roof ! I can't do any good with my Mag Loop anywhere in the house !?!? I had to go ahead and install a HyEndFed EFHW as a sloper. It really does a good job! My little 230 Stick said 10 bands! But 10,15,20 & 40 were the best...
Ah yes, the metal roof acting as a faraday cage. An EFHW sloper is a GREAT antenna.
Love the build out1 Can't wait to see more! 73
A few more episodes to go. Wish I could get to them faster! Thanks for watching.
Excellent Video!!!
Thanks for the view and the positive feedback.
I’m getting ready to do the through-the-wall thing to bring a grounding strap out and feed lines in. I will probably get a box for the outside like the one you used, and probably a patch panel similar to yours. I’m thinking about how to seal up any gaps so mice and insects won’t have a pathway (they can get through a 1/4” hole). My exterior is wood sheet siding and interior is drywall like yours. How did you handle this?
I used a 3" PVC pipe to got through the hole, then spray foamed around the outside of that to close any gaps. Then where I ran the coax inside the PVC pipe, I used electricians putty to seal up around the coax -- it is pliable yet firm enough to maintain shape, and it can be easily removed in the future if needed for repairs or new cable runs.
@@HOAHamRadio thanks for the info!
You make me wish I had an attic. All I have is 3ft of crawl space, boo.😒
I think my peak is 42 inches from the deck. I don't go into the attic space of the main house (insulation and utilities I can't see) but I do get into the garage attic, which is where I run my coax.
@@HOAHamRadio ahh, I understand. No garage here.
How did you bond your antenna to your home ground?
I have a shack ground rod which is then mechanically attached to my house electrical system ground rod with heavy gage copper cable. I do have a Grounding and Bonding video in my Shack Build Out series.
@@HOAHamRadio I saw that. How is your antenna mounted though? I’ve been reading up on grounding and bonding antennas, as I’ll have my antenna in a permanent spot shortly. From what I’m reading, its also supposed to be bonded to your shack and home. This is in case of a lightning strike or proximity strike, any electricity will be equalized through all of your grounds and doesn’t surge into one vs the other.
@@michaelt.9372 At 12:13 of the video you see my panel with all my feedlines. Let's use my 73' endfed for example. It comes into this box via the gray cable through the bottom, into a lightning arrestor, attached to the metal plate in the utility box, with is attached the the shack ground rod 8-10 feet away via heavy gage copper cable; that shack ground rod is then bonded to the house electrical ground rod. If I were doing a tower, or permanent vertical, I would add lightning protection / ground rods at the tower or vertical.
@@HOAHamRadio gotcha. Thank you for the explanation!
I LIKE IT
Thanks for the view and comment. I still have a few more episodes to complete on the Ham Build Out Series.
