RG-58 coax cable length calculation for stub interconnections on the 6 Meter Heliax duplexer.

The length calculated is the electrical 1/4 wavelength and takes into account the 66% velocity factor.

One inch has also been subtracted from the actual 1/4 wavelength to account for lengths in the connectors, BNC Tee and the length on the stubs.

Enter the frequency in MHz:
The Length of 1/4 wave interconnecting cable should be inches.
