30MRK - 30 Meter Resonator Kit

30 Meter Resonator Kit

The 30MRK is a variable inductance that produces an additional resonance in the 10 MHz band when placed in series with the 40 meter circuit of the HF2V. As noted in the HF2V instructions, use of the 30MRK is not recommended when top loading has been added to the HF2V, as with the Butternut TLK loading kit.
30 Meter Resonator Kit for HF2V vertical. Adds 30 meter coverage. Not for antennas using the TLK or TBR-160-S. Maximum power level 200 watts on this band. Note: Addition of this kit reduces 40 meter 2:1 bandwidth to 220 kHz.

Model# 30MRK.
Catalog# 277-02.


The 30 meter SWR should be below 1.5:1 at resonance, and the other bands should not be significantly affected. Slight coil readjustments may be needed to minimize SWR at the desired frequency. The 30 meter resonance should be quite broad and the 30 MRK may be adjusted by stretching or compressing the coil as needed for the lowest SWR on any desired frequency in the band.

The addition of the 30MRK unit will narrow the 40 meter bandwidth to approximately 220 kHz for 2:1 SWR.

The 30MRK power rating is 300 watts input to the final and should not be exceeded. The normal HF2V power rating on 40 and 80/75 meters will not be affected.
