I am using a wire antenna with an Advanced Receiver Research
preamplifier, battery at the antenna, RG6 feed line to the shack,
a Austron 2084 RF multicoupler (multifilter), and then the dummy antenna
adapter to the FS700.
With the hot signals you should have, a simple wire antenna and the
dummy antenna adapter should suffice.

I finally get to help you after several years.

Any antenna will do. But it must draw a certain amount of current. I
use a
430 ohm 1/2 watt resistor to insure that the 700 knows it has an
antenna.
There is a antenna simulator in the manual.
I saw that. It came with full manual.
By the way I feed that and
numbers of other loran C rcvrs from a home brew active splitter so I
have
to have the resistor on that feed.
The 700 has a great deal of sensitivity so it offers lots of
flexibility.
I've considered building an input amplifier similar to what is page
14/14 of the schematics sheets. It has a 3 pole Bessel filter,
alongside a JFET amplifier.
If you have the $ buy a new one. But pretty sure you can't buy them
anymore
from SRS.
They are listed in their web-shop.
Oh, I also have option 01, so I have a nice SC10 OCXO in there. :)
I'll see what a resistor and a patch-cable for fake antenna does to it.
Cheers,
Magnus
