Underwater 2.45GHz Antenna

Merry Christmas!

I am interested in anyone’s experience designing antennas for fresh water communications at 2.45GHz.

Not impossible as I have a link working at 50cm, but need to extend the range to 1 meter.

I am especially curious about how to match a fully insulated dipole using a relatively low end VNA

Likewise, I am intriqued how calculate the length of the radiators and understand these need to be reduced by about 1/9 compared to that in air.

Any feedback is appreciated!
