Default 2 Meter QUAD - Balun / SWR question

I think that the Quad, when tested inside the house had a great match
across
the band from what I recall.


Hi Kevin,

You have just defined its environment.

This thing is fed with RG-8 and I purposely put a whole bunch of turns
into
a 5" coil near the feed point, and ... it resets all the programmable
thermostats clocks in the house
when I key up (interesting RFI huh?)


Do you find the hidden clue when all the excess verbiage is cleared
away?

A whole bunch of turns is not very specific except to indicate you
probably overdid it and negated any benefit you might have expected.
Would it help to say fewer turns on a smaller form?

That, however, is probably not what is responsible for the SWR. You
are going to have to tune the antenna in place AFTER you successfully
isolate the drive line.

Hi Richard

As you know, I have been getting good results with the high permeability
ferrite tubes for decoupling the coax feed line on my balanced antenna. I
bought a bunch of inexpensive ferrites that were intended for absorbing RFI,
from All Electronics. Would it be practical for Kevin, the orginal poster,
to get decent results with a few ferrites covering the coax where it
seperates from the boom??
