[K3PZN-List] Quick Question

[Curt Milton]

Very brief answer - it depends!  

Two factors.  

1. need to consider coax loss versus frequency.  yes
often the larger diameter coax has lower loss, but ...

2. at high enough frequencies the coax will no longer
behave as coax, meaning it will have higher order
modes.  i dont know how high you are going in
frequency.  

coax cable parameters will give info on loss vs. freq,
and highest useful frequency.  another aspect to watch
out for is power handling.  if you are at a total loss
where to find coax data, let the list know what you
are looking for.  

73, curt
