I don't have data. I think the home made TV antenna in the video, is very
much like a bow tie,

Comparable to a 4 bay bowtie. Maybe 6db gain. Brazing rod would be a
little lighter and wouldn't rust. Would work much with a reflecting plane
and above the house clutter.

Twin lead could make a comeback since there won't be such a worry about the
low band interference issue. Actually much less loss than coax. I may yet
change over to 300 ohm window line on my bigazz deep fringe at 40ft and
switch it to the ham shack for 6/2m SSB work and DTV DX. TV DX won't be
dead, you will just have to know where to find it

Twin lead could make a comeback since there won't be such a worry about the
low band interference issue. Actually much less loss than coax.

Maybe... when it's new, of the right type (e.g. tubular), clean, dry,
and carefully installed.

My understanding is that the performance of 300-ohm twinlead
installations tends to deteriorate significantly after a few years
(sunlight and ozone attacks the twinlead, and dirt and pollution
builds up) and during wet weather.

Last time I used twinlead, except for fiddling around, was on the family
TV antenna installation using an Allied Radio Corodized VHF antenna,
with Beldon Super Permaohm 300 ohm shielded twinlead. Good stuff.
