Let's hope Marlene Dietrich is in the lead.

If you buy some make sure you get the directional arrows the right way
round, you don't want to have to rip it all down and clip it back again,
also you may wish to get an aerial made from nitrogen free aluminium ...


And if you get some company to "burn it in" for you don't forget to
leave it unplugged for at least a week before use to let the burn in
electrons discharge into the air.

Summary: If you have spent £100s, or maybe £1000s, on connection cables
don't expect to hear any improvement in sound/vision until they have
burnt in for 500 hours, or longer.
It would be a bit of a bugger if the dog chewed your Russ Andrews cables

They probably sell the offcuts as up-market dentastix ...

Super-crunchy copper centre, premium chewy XLPE bedding encased in
anti-bacterial silver nano-braid floss with the PVC outer heavily loaded
with carbon black means more "blaming it on the dog" either ...

The industry is very excited by the new directional cables.

Cunning.

Because the cable is unidirectional and AC (bidirectional) signals need
to be carried two parallel cables will be need - one for electrons
flowing in one direction and the other for electrons flowing in the
opposite direction.

Obviously these cables will need to be carefully matched pairs. Just
taking a length of cable, cutting it into two equal lengths and putting
them side by side will not result in an adequate match.

That's where the dual 'shotgun' cables come in. Providng you cut them
across with a square end they will be precisely the same length.

I have found a problem with these cables though. Because of the
requirement for near-vertical operation it's not possible to tape them
to the boom of the yagi, and they tend to stretch a bit when you have
more than about 10m hanging directly from the balun.

I recommend this even with ordinary cable, using diodes to ensure the
current goes the right way. This allows electrons to migrate steadily
through the wires. If you pass AC through a single cable, the
electrons oscillate back and forth, never moving more than a few
micrometres from their starting position, and gradually become stuck
resulting in a "muddy" sound.

Perhaps Russ Andrews could be persuaded to sell a line of
technology-friendly pets.

I heartily agree. Electrons get bored going backwards and forwards all
the time and never really getting anywhere. Give them a break, by making
sure they can flow in one direction only, then they'll think they're
making progress and will reward you with a sparkling performance...

Perhaps Russ Andrews could be persuaded to stop selling snake oil too.

I think most of them are dead by now.
