I am familiar with only one setup. A sewage plant. The opperator
controls gate open or close, and the pickup prevents the gate
from ramming into the vehicle.

You must have many guests and visitors to warrent this setup you have,

HD has it in several locations in our local stores (plumbing and maybe also
electrical areas) - may be hard to find cuz most people don't know about it.

I think it's the "typical" setup to have a way for guests to leave.

You have to note that I considered wiring a push-button (doorbell type)
switch in the house to open the gate for guests to leave but I can't even
see the gate from the house since it's about 500 feet down a hill to the
gate - so that would be a safety problem.

I guess I should walk everyone to the gate but that seems like a lot to ask
of me. But I think most people have the following bare minimums and common
electronics.

BARE MINIMUM ELECTRONICS:
- Keypad & remote open (with automatic close)
- Stall force setting so nobody gets crushed

EXTREMELY COMMON ELECTRONICS:
- Intercom for convenient entrance of guests
- Exit wand for automatic open upon exit

SPECIALTY ELECTRONICS:
- Telephone-operated gates (open/close from your cell phone)
- Video feeds on the gates (so you can see who is at the gate)

It seems we are talking about -- at least that's what's included in
his kit -- "Scotch 23 High Voltage Tape"**, but when I search on that
at the Home Depot site, I get 2 hits, regular vinyl electrical tape
and packaging tape. When I search on "Scotch 23", I don't get
anything.

Now HD and Lowes have the worst webpages I've come across, so maybe
that doesn't mean anything.

The one easily visible thing I've noticed about this tape is that it
is wound on a white plastic spool, instead of a cardboard spool. It's
thick and has a backing layer that has to be removed to use a piece.

Are we talking about the same thing? Do they really have it at HD.
I looked years ago but couldnt' find it.

It's expensive. I think I paid 11 or 12 dollars a roll, but it's great
for special uses.

**Other listings for this tape call it self-fusing. That probably
refers to what I said about merging into a big blob. Other
descriptions make reference to the polyester liner, the backing layer.

But so far, I've found little reference to how it is to be applied.
Just one line "Physical and electrical properties are unaffected by
the degree of stretch." and I don't see how that is even true. OF
course if it is stretched to thee times its length and it's 2/3rds
thinner, it's going to have lower strength and electrical insulating
qualities. They even have a chart about that on page 3 of the same
data sheet.

Self-amalgamating they call it here.

BTW, if you don't stretch it, it won't stick to what's underneath it.
There is no adhesive on the tape.

I'll go to Home Depot today and let us know what I find.

In hind sight, I should have bought the WIRELESS vehicle exit sensor setup!
