I believe the 16 Satellite, GT-80 timing GPS modules are the same pin-out.
Pin1 is the closest pin to the antenna socket.

Hi,
Not too long ago there was an interesting discussion here about RF
connectors. I have always wondered about the F connector - used by
the boxload in TV distribution.
Are they any good for anything else? Just curious. Thanks.

Steve,
Several of them smashed flat, stacked up, and jammed under a door make a
low-quality door stop...

The quality varies a LOT. The good ones are the water proof ones they
use outdoors. They are made to fit RG6 quad shielded cable and must
be installed with a special tool. They are 75 ohm connectors.
There are also many junk f-connectors used with rg58 and rg59.

They're half decent 75 ohm connectors out to about a GHz if you do that.

Hi Steve:
Many GPS receivers are designed with Type-F RF inputs in order to make use of
the low cost TV coax.
But even if a GPS receiver has a 50 Ohm RF input you can still use 75 Ohm feed
line, see my low cost 4-way splitter:

For most hobbyist use (nano
The F connector makes up an extremely cheap connection for TV and satellite
broadcast antenna cable. I use it even for my GPS antenna cable but I'd
rather not recommend it when a stable and repeatable connection is needed.

Yes they work but more

Maybe a silly question but isnt the phase response of the filter important
in this application ?? notches have fairly vicious phase shifts.

It is easy to use filter software to design a filter like this,
but how well it
Actually, the opposite is true. Notches have the least phase
shift at the frequency being passed, which is what matters.
It is true that the phase shift at the notch frequency is
uncontrolled, but that is not important. The HP8662A
had an interesting PLL synthesizer where they had 10 notch
Greetings,
I have used the longitudinal compression F connectors for some time now with
several GPS units and RG-6 cable. They certainly appear to be waterproof
and quite sturdy. Not inexpensive but very serviceable. I found a kit with
the installation tool and connectors and separate
