[Amps] amp relay interconnection

[Steve Flood]

When inter-connecting input and output relay RF contacts, what conditions 
warrant using coax versus wire?  My layout will be fairly compact with no more 
than 3 inches of conductor needed between any of the relay connections, as 
follows;

Input SO239 to input relay common: 2 inches.
Input relay NC contact to Output relay NC contact: 3 inches (passing thru 
grommet in deck between rf compartment and underdeck input compartment).
Output relay common to Output SO239: 1 inch.
Input relay NO contact to input PI network board: 2 inches.
Output relay NO contact to load capacitor stator: 3 inches.
