[TowerTalk] 1 5/8" hardline to N female?

[Daron Wilson]

You can get that EIA flange fitting for 1 5/8" heliax probably from Tessco,
certainly from Andrew I imagine.  You probably will end up getting an
adapter from that flange to an "N" connector.  You'll need a 'bullet' as
well, the nice little 'double male' fitting with an insulator on it that
goes between the two center conductors.  Perhaps the antenna manufacturer
can provide you with the components, it is worth doing it right for the
quality of antenna you have.

Good Luck!

Bill:

     This looks like something called an EIA Flange.  Typically used on
high-powered transmitter circuits like in the Broadcast Service.

     Suggest you do a Google search and look for sources of such connectors.
