In a word, YES.

Also SWR problems. Intermintent of transmit and receive. Possible RF burns if your touching it while transmitting, just to mention a few.

Does that go also for the crimp on type "Solderless" coax connectors? And if so, why even make these TVI causing type of connectors for the general public to buy??

Wolverine,

YES,

These connectors are made for those who do not have a soldering gun.

They are cheaper to put on Antennas than soldering, and for truckers & others on the road when they snag / break an antenna or coax and need a Quick fix to keep going.

Always check coax for short's weather useing Crimp On or Soldered connectors.

1 drop of solder shorting center to shield can wipe things out quick.

And the only Connectors & Reducer's I Use or Recommend are AMPHENOL.

A few cent's more but well worth it.

Just my thought's.

Crimp type connectors are the only close alternative to solder type. Many of the best flexible coaxial cable assemblies are of the crimp/solder type. In this case, the center contact is soldered to the center conductor of the coax and the shield(outer conductor) is crimped to the shank of the connector.

In the case of a crimp/solder termination 2 major advantages are achieved. For one, the center conductor and contact ARE soldered with little or no heat damage to the dielectric and jacket of the coax. Second, the shield is crimped with a 'hex'(hexagonal) crimper which ensures a good electrical connection and NO heat damage to the dielectric and the jacket.
