6. Is there anything else I should know?

You're going to have backache.

===========================

In all probability he will lay down far more and longer than necessary,
anyway.

Is Sloan's Linament still available?

Nah, the chances are that, like so many other cowboys, he'll just open
another company and carry on regardless.

Unless they get banned from holding directorships.

Not unknown for someone with a score to settle to buy up the debts of a
small company and send it to the wall. If done correctly, the wayward
director is them in the p***

How would that work? Surely you'd just be buying written off debts from
a liquidated company. More fun to liquidate the offending Director.

Back in the 50's, it was common practice to smear grease on
automobile battery terminals to keep them from corroding.


Still is in the UK. Also I assume in the USA, one of my cars was made in

the
USA and came with grease on the terminals.


Guys, the last time I checked, this was not rec.car.battery. We're talking
about antennas and RF, not DC connections to your car battery. Using grease,
even outside the made connection, will eventually penetrate the spaces.
Maybe this doesn't matter to the 50-100w user, but it matters to high power
connections, the most notable of which is lightning.

I may have missed something here but in my case I only have a 1/2 acre
'clear' under my tower. Because of the limited area
I chose to use a grid system of insulated solid wire an inch below the
surface with spacing of 3 feet per side of the grids.
I then removed insulation ar cross over points and crimped the wires
together, the crimping then made it quite easy for the solder to flow.
Tree roots have pushed up the wire in a couple of places but the rest is
unseen. I don't do to much work with verticals so I can't comment on the
sutability of this type of ground and have not read anywhere of any
comparisons to the normal radial
type ground especially for use over ALL of the amateur bands.
Food for thought. Judging by the number of responses recieved by the poster
there is a whole bunch of knoweledge out there on how to mess up your lawn
( yard over here)
P.S. get a mechanised pizza cutter to make the wire slots and place it on
the wheel of a wheel barrow so as not to alarm the neigbourhood

If that Ian's garden is anything like this Ian's, in some directions he
will probably be forced to lay down fewer and shorter radials than he'd
like, and he may try to make up for that by overdoing it in other
directions.

He'll probably give up when his back gives out... and still trying to
work out exactly what you meant by "necessary".

Certainly, from any good horse-doctor.

I do recall that once upon a time in Yorkshire, two completely new
products came out in similar-sized tubes. One was Deep Heat Rub for bad
backs; the other was Evo-Stik Impact Adhesive. Lighting were bad i' them
days. You can guess the rest...

Art, you're a genius!

SM2CEW's website describes a radial plough which attaches to the back of
a tractor, and can lay a full-sized Top Band radial in 2 minutes. I had
been lamenting the lack of a Volvo tractor (or the space to lay such
long radials) but a blade attached to a wheelbarrow might just do it...
or even to the lawn mower.

Not if you make the electrical connection first, and then coat with
grease.

You wouldn't paint the radials ends and then make the joint.

OTOH, perhaps you would.

PS: Paint can be a dielectric too......

Use a car battery clamp and plenty of grease.

Thanks for the injection of sense, Brian. As I say elsewhere, you
wouldn't paint it first then make the connection.

OTOH, perhaps that's whey no-one has heard Bean on the bands.....
