Quite interesting, I think.

Some good research there. Always meant to do something similar myself.

Check out the Group A widebands! They are shockingly bad.

A lot of the botchery round here consists of large aerial firms "upgrading"
old Group A aerials to wideband "digital" high gain ones and charging £250
or so for the priveledge. They use the old mast & fixings too most of the
time.

Also nice to see that a good quality 18 element GRP A is only about 1.5db -
2db down on the monster XG16A.

All very good research & proves what we have thought about the DAT45 etc for
a while now.

This layman found the site interesting.

I'm not disagreeing (honest) but I'll be brave and courageous (i.e.
foolhardy and stupid) and also say how nice it
was to see someone recommending a wideband aerial (DM log) for strong
signal areas. For those of us who can see the Crystal Palace mast from
the roof, it gives a good signal now *and* is future proof - the latter
a big plus over the group A aerial some seem to recommend by reflex.
(And yes I do know now that CP will remain Group A after the switchover,
but who knows what the next 25 years will bring, and SWMBO may well live
that long.)

Yes, but the aerial probably won't last 25 years!
I can see both sides of this. Logs are certainly the ideal choice in some
situations, but more often than not, for CP, a quality group A will be the
best choice.

I installed mine in 1977. It's still working.

I hope you celebrated accordingly last year?

IIRC yours is a Fuba or some other similar bit of kit that they don't build
like that anymore? My in-laws are still using an Aerialite 10A from the
1960's.
I don't expect many current aerials will last longer than 10 years,
especially some of the flimsy X designs.

This is a fabulous resource, and the first EVIDENCE (rather than the usual
prejudice and hearsay that so many here indulge themselves in) that the
DAT45/75 is not the highest gain wideband aerial available.

It's a shame Justin didn't measure the rejection ratio off the back, because
here at Felixstowe - where we must point inland at Sudbury - co-channel
interference from Holland onto the back of the aerial is a serious problem
whenever there's a lift on.

I don't know if Justin frequents this place, but my thanks to him anyway.

One of these fine days the bloody thing will fall down Charles, and you're
going to be short of something to say!

Why not? We had one installed 23 years ago and it is still performing fine,
although not for much longer as it's coming down tomorrow.
