Excuse me?

Plug a TV in and wiggle the aerial until you get acceptable signals on
all available channels.


I would expect no better from someone of your standing. Always looking for a
bodge rather than do it properly.


I AM an engineer, and believe me, you can get bogged down in dials and
scope traces far too much.


Bless!

In the end its a quality picture you want, not some arbitrary reading on
a meter.


AH, now I see... You don't have any measuring equipment and resent the fact.
That's what comes from being a cheapskate.

Now please can the unwarranted abuse.


My guess is that neither does the OP.

I have had many many years peering into scope traces and dials and
needles..it has its place, but for something as utterly trivial as
putting up an aerial its a complete waste of time.

The main lobe is sufficiently braid that accuracy to the last degree is
not essential. What is FAR more relevant is usually aligning the first
(or any suitable) major NULL with the direction of any strong multipath
interference.

A field strength meter is of no use in that context. You need something
that will display the relative strength of short time delayed signals.

The cheapest precision instrument that does that is a *television set*.

A little knowledge is a dangerous thing Andy. Real professional
engineers with 30 years plus experience know that expensive test
equipment is useful, but its not the be all and end all of design or
installation, and its often not the quickest approach to a problem.

You can spam away all you like selling your 'professional services' but
I will continue to respond that a half a brain, a little time and a TV
set is far more appropriate answer to the problem than your expensive
services.
