[amsat-bb] why not to buy an M2 antenna Sealing Coax

[Rich/wa4bue]

I am not a fan of COAX Seal, it tends to migrate into the connector.

In the Hampton Roads area, a NAVY town, we use the old NAVY way:
* Light application of high great Silicon
* Double sided electrical tape rap
* Electrical tape rap
* Spray lacquer over
* Nylon tie on each end

Great seal!
