What I read here no switch box will be needed.
The radio will pick the element that is most resident to the frequency your
scanner locks onto and will let you receive accordingly.

try a homemade vertical di-pole with one element for each band you
want to receive soldered to some good coax. For protection from the
weather
you can seal it in a suitable length of PVC pipe with endcaps.

For the bands you mention above, your elements would be: 17", 6", and
3.3".
One of each soldered to the center conductor and another of each soldered
to
the shielding. This is not a transmitting antenna so no impedance
matching
mechanism is necessary and the coax can run down alongside the lower half
of
the di-pole.

To calculate other lengths: FEET=234/MHz (i.e. 17'=234/160.000).

Hey Frank,
That is interesting and I know of the thinking behind it. Have you or
someone
you know (maybe someone in this group) ever run an antenna like that and
what
are/were the results. {?}

This might sound silly, but you wouldn't need a switch box would you to
switch
to each 'antenna.'?? You mean you could use this 'one' antenna and just
run it
straight to your scanner and as you searched different parts of the
spectrum
the cut antenna would automatically work for the part/areas you were
scanning?

Thanks for any reply by anyone. :-)

**I know in SWL you'd have to use a switchbox for a setup like that.
