MFJ-1704: Excellent, well built.
AS with all products we use in our stations, it is our responsibility to check them for the function advertised before placing in service. Mostly there is no problem but if a ground is off, these switches can and should be inspected and can be easily adjusted. One switch sent was on the mark and the other needed a slight squeeze of a ground connection to the lightening protection gas discharge unit.

MFJ-1704: Excellent, well built.
This antenna switch gives me the option for my SPGP to have incoming and outgoing cable on two different planes to prevent crossover.
