I have an old 2-meter Ringo Ranger on top of the tower
that has not been used for some time. I wonder how it
will do for six meters?
None of my SWR boxes cover VHF so may have to just
give it try and see what happens.
Wish me luck
It was a good idea that DID NOT work. The SWR as shown
on rig's s-meter was terrible and I could tell it was not hearing
as well as the fan dipole.
Well Dick, you only asked for positive responses, and you go none...
so no surprises.
The matching arrangement on the Ringo is a quite narrow band one, so
you should expect that it will not work well on 6m.
It is not uncommon to hear of people on HF using a 11m end fed half
wave with narrowband matching (ie similar to the Ringo) on the lower
bands (eg 7MHz) with the 'assistance' of an ATU. I quote 'assistance'
because the ATU does assist in obtaining a good VSWR for the
transceiver, but probably converts most of the transmitter to heat. A
good example of the failure of an entirely VSWR focused approach.
An ATU can hide a multitude of sins.

It might actually be better if the phasing stub were replaced by a
short !
