Using brass or copper to join copper would require getting the bond metal Yes it is and it's called CadWeld. Their "OneShot" products are awesome. Go to erico.com click on the Cadweld button and then
The following two companies make the best units. Check out the technical literature on their websites for the complete skinny on what to do. I never disconnect and never have had a problem; even with
I can't help but make a few comments found below: Sean rf wrote: Suggestions for grounding: When attaching your #4 solid copper to the ground rod, use a non-oxidizing compound between your ground cla
I also believe both the PolyPhaser and ICE website technical articles warn against non metallic towers. I don't recall their exact reasoning but I believe it's along similar lines as stated. If you'r
All that dipoles do on 160M is to warm the clouds above your house. I'd shunt feed the tower. That's what I do and it's a killer. Just remember that whatever you do, you'll want to investigate low ba

What I would do is to attach a pipe clamp (muffler clamp or actual piping clamp) onto the mast above the thrust bearing. Now the weight of the mast/ants will be borne on the top of the bearing. Then
Using a gin pole to support the weight of this assembly might be pushing it's limits but I must strongly remind everyone that using the keeper bolt in the pointed top section to hold the assembly is
I new to 160M and am always learning but I'd like to reiterate a main point in your msg Rich and that is hearing is usually more important than transmitting. If you can't hear 'em you can't work 'em.
And if I may add a comment: Jim Jarvis wrote: 6) revisit #3....somebody suggested an on-ground beverage. If your ground is actually 30' below the earth's surface, or 20, or 10, this might be a good s
Go for it. Run don't walk, you'll never look back. I have one up turning my 3 el. 40M beam, 32 ft boom, 42 ft. elements. It has no trouble with that. I really like the small control box; you use an e
I'd like to just reiterate that it doesn't matter how many thrust bearings one has on the mast, those centering screws are not meant to hold any of the vertical loads of the mast/antenna assembly. Th
Yup, the Spid has a very simple yet robust design. Nice worm gear system, no brake, no stops. Just two wires for the motor (12-24 VDC). Direction is switched in the controller by simply switching the
If the tower has angle iron type of legs, then you lower the tower section into the hole after the rebar cage has been installed and support it off the bottom of the pit with solid concrete bricks. I
The following statements are my personal opinions: 1. I hate crank ups. You can't climb them (if you like your fingers and toes) and therefore you must use a ladder which is far wobblier than a nice
Can we quite this thread and get back to towers and antennas? Kwityer--ing everyone; this isn't eHam! Sri for that shot but really now. And what are popups anyway? I use Netscape and have popups disa
If one looks at the photos of some installations I see slip joint type of connections rather than the flat plate ends shown on the pdf views. I'd imagine they'd make an interface if there is a differ
I would agree 5 radials just won't cut it and your theory of impedance changing during rain is probably right on. Also your planned number of radials of 12 - 24 is also low. The best bet is 60 1/4 wa
I wish to apologize to the group for stirring this debate up. I think it's good discussion but let's not rehash old information that is already in the archives. I think I started this by responding t
Wishing to brag; check out my new 40M antenna & tower erected this summer/fall. It really works well. The website pages have a lot of info and piks of the tower install, the antenna mods, and antenna
