Re: Topband: Replacing F Connectors with BNCs

["Tom W8JI" <w8ji@w8ji.com>]

There are push on F connectors, and I use them, but I use them wisely. I 
minimize my dependence on having a perfect shield connection as much as 
reasonably possible.
For example, my swap over from house operation to contest barn operation is 
all via push-on F connections. I have zero problems with shield ingress. I 
would not use them out in the rain, or in a situation where I could not 
mitigate small issues with shield connection resistance.
A push-on F is about as reliable as a BNC electrically, although physically 
it has no mechanical locking.
