No. Ordinary lead/tin solder is just fine. I prefer 64/37 "eutectic"
solder as it goes from liquid to solid without passing through the
plastic phase. This tends to result in better joints.
It is important to ensure that you moisture-proof all joints. Use
either weatherproof connectors (BNC and 'N' are supposed to be) or use
a sealant like Coax-Seal over the connector and coax.

That should read "63/37"

I would think that silver solder is not necessary and might even be a poor
idea as with the additional heat one could destroy the spacing between the
center and shield. I know that I destroyed (melted) enough of the dielectric
on a mag ground wire by just trying to solder a pig-tail ground on the
shield that the engine would not start. Ohm meter still said no connection
but the engine would not start until the shielded wire was replaced.

Hello,
Brian is CORRECT about the 63/37 eutectic solder. This is
the best solder for ALL electronic work as it is the LOWEST
melting point of ALL tin/lead solder joints!
