twin feeder doesn't radiate. Mind you, that doesn't apply to a G5RV
where the 'other' bit of the feeder (the bit that should be 75 ohm
twin) is coax. Where it is, both the coax and the 300 ohm twin will
radiate. [IIRC, the original G5RV was 300 twin all the way to the
shack, where it fed via a balanced output ATU.]

Sorry, but you were mumbling, and I was having great difficulty deciding which side of the fence you were on. Next time, you'll need to make it
much clearer about what you're burbling on about.

So balanced transmission lines do radiate ( and pick up) but not very
much ; It's about -45dB at 28MHz for 450ohm line - it depends on the missmatch too.

I had to look at twin line feeder radiation recently. I'm making a
432MHz co-linear array of 8 x 2 eles fed by 450ohm twin feeder
phasing sections and thought that I might have a problem . The
dipoles are folded to give 200ohm, hence I've a missmatch.

Is it not a bit distasteful to imitate the name of the established firm in the
field?

What sort of waves are you hoping to launch with that, Bri?

Horizontal . It's a scaled version of this one. Https://www.qsl.net/df3lp/projects/8x2e144/index.html. I'm using
galvanised fence wire instead of stainless steel.
I play contesting at a high spot near Stranraer , and realise almost all
my signals come from a pretty broad arc to the SE. An antenna that
covers that arc seems useful. I can extend it to 10 x2 if it works.
I'm making one of the 2 eles to make sure it works before doing the rest.

You'll probably remember the late G8BHH used to run a colinear array
as GW8BHH/P back in the 70's/80's.
