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

http://www.surplussales.com/Connectors/EIA-6.html it seems that steps aren't
all that unusual That 3-1/8 to 1-5/8 adapter looks pretty short to not be a
sudden step.

Looks like part PE2231 would work well.  Note this adaptor has a gas
fitting.  I guess this is for pressurizing the 1 5/8 cable with nitrogen.
It would not be needed for low wattage.  The price of this "used / removed"
item is $295!

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.
