How to install PL259 Connector for Ultraflex7 (Warning: read description below)

Описание: We have made a tutorial for those who use standard PL259 connectors, although we highly recommend our new generation ones.
WARNING:
Some of you, based on old habits, matured in the old days of RG 213/U and RG8, (made with compact Polyethylene and 66% velocity ratio),
WILL OBJECT THAT WE HAVE NOT WELDED THE BRAID.

WELL WE DID IT DELIBERATELY!

From studies carried out, we have in fact experienced that in order to be able to weld the tin on the external hole of the PL 259 type connector, it is necessary to bring the temperature of the connector itself to about 300°C. This certainly does not damage the Teflon of a good quality connector, but can easily deform the expanded Polyethylene dielectrics which melt at 100-110 degrees C.

To give you excellent impedance stability an optimized VSWR, and exciting attenuations, M&P dedicates great efforts to maintain the tolerances of the dielectric diameters within a few hundredths of a millimeter.

Therefore, bringing the connector to about 300 ° C, to continue an old tradition, means giving up the very high performance of ANY modern expanded Polyethylene coaxial cable, with a velocity ratio of 84-87%. (depending on the models).
OBVIOUSLY WE DO NOT RECOMMEND USING THESE OLD GENERATION CONNECTORS!
We strongly recommend the Messi & Paoloni watertight compression connectors, specifically designed to take full advantage of our products, reduce the risks of thermal stress, while maintaining the exceptional shielding efficiency typical of all our models.
