Re: Topband: Radial Attachment Plate
I had a DX Engineering radial plate on my P40A 160m vertical and had zero corrosion. You could cut one in half to go around the tower. Rolling up multiple attached wires would likely become a tangles mess. You should be able to find suitable stainless steel angle at Mc-Master Carr, drilling a Ø5/8 hole is easy. You could also drill multiple holes and bolt the radials directly to the angle. https://www.mcmaster.com/products/angles/material~stainless-steel-2/corrosio n-resistant-316-stainless-steel-6/ John KK9A Stan Stockton k5go wrote: Jim, Thanks for pointing me to that review.

Of course there is a huge difference between 75 or 100 feet and 5 miles from the salt water regarding corrosion. My plan is to get all my radials attached and then perhaps spray the whole thing with liquid electrical tape and deploy it when I am there for a few months a year.

There are several sizes and the smallest one which would be good for a vertical made from aluminum tubing would only cost $7.99 delivered. Can't beat that deal. What I need now is a stainless steel angle the right size and preferably with a 5/8" hole to mount an SO-239 to the radial plate. 73...Stan _ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector

Topband: Radial Attachment Plate
In preparing to head to ZF9CW in about ten days, I wanted to take something that would allow me to do a better job on my radials under my shunt fed tower. With the thing so close to salt water the detriment is that everything corrodes in a short period of time. I was looking for something to help solve my problem and found this on Amazon: https://www.amazon.com/dp/B08N6X576D?psc=1&ref=ppx_yo2ov_dt_b_product_details You can add however many you want to size a square or most any shape to surround a vertical or tower. I will likely use 8 of them to make a square to go around a 55G tower if I decide to use that one someday. In my case, since I cannot run radials onto my neighbors property I will only use three of them to go around my 25G tower. The holes are M6 size. I put together four of these plates in a square and have stainless steel M6 hardware installed in the 28 holes. Even for this small version you could have 3 radials to each connection point and have 84 radials. If you are interested send me an email and I will send you a picture of the thing put together. I think it will help with my corrosion problem and wanted to share the information. 73...Stan, K5GO/ZF9CW/ZF5T _ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
