I've been reading a lot of older threads about using ground shields (mesh or solid copper ground radial plates) at the base of an Inverted L for 160. Several contend that AM broadcast stations use co

You can use mesh or chicken wire. You want to use stainless grid. Chicken wire will probably rust away pretty fast. You can hook up additional radials to the mesh. On 8/24/2018 8:21 AM, Chick Alle
I check out the near by body shops for bent aluminum wheels. They make a great secure base for attaching radials. Bob. KT3RR Sent from my iPhone _______________________________________________ ______
I've used the LJE (Lance Johnson Engineering) Radial Plates for some of my HF Vertical antennas. I've been trying to find a link to order another one, but haven't been successful. Does anyone know wh
DXE makes great radial plate. That is really not what the question is about. LJ I've been reading a lot of older threads about using ground shields (mesh or solid copper ground radial plates) at the
I do have a DXE plate, but then you have to buy the Saddle Clamp, and other pieces separately. I've always had good luck with the LJE round plates, but their link seems to have disappeared. LJ --Orig
Broadcast stations on medium wave use copper mesh around their tower piers, extending out around 20 feet, in cases where the tower is voltage fed, i.e. around 190 degrees. In those cases the v. at th
I have a very old 10.5' aluminum satellite dish out in the woods. I keep thinking I should put this at the base of one of my 160m verticals, right on the edge of the woods where the trees meet the la
A radial "plate" is highly overrated. Simply tie all the radials together at the base of the vertical. See the photo on my QRZ.COM page. 73 Don N8DE _______________________________________________ __
Maybe I could get my wife to plant some ivy on it to eventually cover it all up camo-style. Would it make any difference? ?? Mike VE9AA Not to the ivy, and I'm certainly ok with it. Green is good. Mi
I totally agree. I can't think of a single valid reason why a plate is even a little bit better than simply a tie point at the base. I've often wondered why folks don't simply use the addon bus bars

I have used those electrical box expansion bars (with built-in screws) for several radial installation. They do, indeed, work well and they have been physically and electrically sturdy. Regards, --Ki

The DXE radial plate is $60.00. It is Stainless and has 60 connection points, allows for other connections such as your coax connector. I found one buss bar at Lowes with 15 connections for 10 buck
I'm not sure what the metallurgy of the screw and bar would be like in conjunction with solder. Of course the bar should be fine with copper (and I think even with aluminum in alkaline soil environm
One issue that could occur with a copper buss bar, especially if you're slow at adding radials is that copper corrodes pretty quickly. It might be difficult to clean out the black oxidation in the ho
Regarding using ground bus bars as tie points: If you can still find them, copper ground bus bars with screw terminals would be ideal as you could then braze the wires to the bar. You could fit sever

Regarding your recommendation to use MAPP gas. Does the new stuff get hot enough? I understand there has been a downgrading of heat production with the "new" MAPP gas. You could probably shove a bu
I just wish the DXE radial plate had the holes tapped for 1/4-20. It's a pain getting to the underside with a wrench to remove the nut when you have a bunch of radials attached. 73, Roger ___________
