Re: Wimo 13cms yagi


Dear John,

The 18GHz N-types- non-slotted outers- depend critically on uniform contact between the front of the outer on the plug and the step in the socket.

If contact is incomplete, suck-outs result as with your load. 18GHz plugs usually have flats to enable them to be torqued correctly- 1.5 N.m

For general use at frequencies up to 11 GHz I prefer the slotted outers, as they engage against the sides of the socket outer and torque is less critical.

7/16 DIN connectors require contact as the 18GHz N types and this requires very considerable torque- 25 N.m.
