The device is an antenna and receiver in a mast head package, with a
few yards of
multi-core flexible cable coming out of it. It is a white mushroom 3

It takes 8 to 40 volts DC to power it. it has 1 PPS directly out of
it, and if you like to wire a
serial plug onto some of the wires you can plug it into a PC and
small program from the manufacturer which will give you access to
GPS type functions and options in the unit.
As it comes it will deliver 1 PPS signals which is all I ever needed.
It has been
giving a nudge to my HP10811 oscillator. Indoors, next to a window which
sees a bit of the sky, it gives the 1PPS signal about 50% of the
is quite enough to keep me on time.
