Antenna Preamp

Is there a CMOS op-amp with low noise, good common-mode isolation, and unbalanced output available? I would like to use it in a loop antenna preamp in a location that has an extremely high power-line noise level. 

E-mode whips with a preamp are definitely unusable. This antenna would be untuned and intended for use below 30 MHz.
