Oh yes, and Mark, tell them about how hard it was climbing up there.

Ssshhhh !


OK I'll let the cat out of the bag. Mark said he had a bad leg as they
were on the foothills, so the missus gave him a piggy back.

Why do they persist with these horizontally polarised FM aerials? What's
the point?

How come the gain for both FM and DAB just happens to be 0dB? For
various reasons that seems most unlikely. And is it dBd or dBi or what?

These are no good for DAB, they're horizontally polarized and DAB is
vertically polarized.

They're not a great choice for FM in many places either because vertical
polarization of FM is common now, especially for local relays and local
stations.

My HP Band 2 aerial seems to work very well for Band 3 DAB. At least far
better than the bit of ribbon supplied with the tuner.

Is one indoors and the other outdoors?

That can make a huge difference.
A wrongly polarized outdoor aerial can easily beat any indoor aerial.

A properly mounted outdoor aerial should match the polarization of the
transmitter at least as a first try. Weird things can happen with
distant signals but it'd be unusual for anything other than a very weak
distant signal to come in best with a properly mounted (clear of
anything else) outdoor aerial with the "wrong" polarization.

Put your Band II aerial vertical and both will work even better!

Trouble is that it's well out of my reach. I put it up in 1979 when I was
a lot younger.

My vertical Band II (unfolded) dipole works in Band III just as well as
a Band III (unfolded) dipole. (Yes, I've tried it)

Curiously enough I have one of those in my loft, bent to fit around a
rafter, and feeding into 30ft of coax. At the other end is a DAB
receiver which is working just as it's supposed to - negligible errors.

I never expected it to work - but it does, so I've let it be.

Are the two aerials both in the room or both on the roof?
