Hi Guys/Gals,
Be careful of the so called "solderless" connectors, and those
purchased from off shore.
I have a good friend who was extolling the virtues (& price) of these
and had installed them on his phasing lines and HB power divider
(chassis mt type Ns), for his 2M array. He took this into the field
to make some MS contacts, from rare grids.
After installing the system (this was not his first field trip with
it) he experienced a high VSWR, and after much trouble shooting and
advice from his accompanying buddies, they discovered that the center
pins, in not only the coax cable connectors were not secured in
place, but even the chassis mount connector center pins were loose
and movable. IOW the male (& female) center pins tended to pull way
from the main connector.
I have seen this happen before, when due to temperature changes, the
center conductor of some RG-8 size coax types, try to expand/contract
and pull away non captivated center pins. Therefore only utilize
those connectors that have their center pins fully captivated. I
also advise to solder them, even when using a crimping tool for the
shield connections.
