Thats fine
If the 3 v rcvr complains connect a 450 ohm from the antenna to ground that
should make it happy. The resistor really isn't picky

Is it reasonable to to use a GPS distribution amplifier (viz. HP

should I get a bias tee? The internal operation of my electronics
is largely a mystery to me.
Bias tee would be best
The HP58516A has no external DC power connector (unless it has the option
05Q). The receiver feeds the HP58516A and then the antenna. Maybe your
antenna works downto 3V. The bias tee needs also a DC-block, otherwise you
will put the 5V to the receiver's input too.

It depends on the antenna the old ones were 5 and the new 3.3V. I believe
5V on a 3.3 antenna is bad and the other way around you loose gain.
On the rcv side some rcvrs want to see a bit of current draw to say an
antenna is attached.

Yes, my plan was to attach a 5V receiver to power in
