[TowerTalk] PL259 Connectors Part 2

[Roger (K8RI) on TT]

Although it's strong and looks good, I'd think it'd create a much larger 
impedance bump.  OTOH those impedance bumps are so small at HF, it'd 
probably take a lot of them before any of us would notice.  Even with 
all the connectors I use The AIM shows a healthy return loss and you 
really have to look to find the impedance "bumps". So at HF, even with 
10 connectors between the station and antenna there is very little loss.
