13.56 MHz is an ISM (Industrial, Scientific, and Medical) frequency. There
are 7 frequencies allocated by the FCC for that purpose in that specific
ISM band - in a NON_RADIATIVE MANNER. Why are you connecting an antenna to
a 13.56 MHz source?
Most of the MetCal soldering stations operate on 13.56 MHz.

It isn't clear to me what the situation is here. Do you mean you have an
antenna connected to a 13.56 MHz signal coming from a signal generator or
transmitter of some sort, and you wish to transmit that13.56 MHz signal?
Or, you have an antenna you are using to receive a 13.56 MHz signal, and
you would like to prevent interference picked up by the transmission line
from being brought into the shack? Or you have something else (NOT 13.56
MHz) you are trying to receive and the 13.56 MHz signal is interfering with
it? Please clarify.
