That's because I know the shortwave posting is the exception rather
than the rule. I wouldn't care if you made the occasional off-topic
post, but you post so much crap to this group that it's virtually
unreadable. That ain't right. You can get your 'viewpoint' across
without undermining the overall shortwave-related purpose of the group.

Why don't you attack RHF, Peeing Eye Dog?

If RHFposts off-topic, it's usually in a thread that someone else (most
likely you) started.

I do wish that Peeing Eye Dog would make fewer off-topic posts, but he
makes fewer than you and there are only 24 hours in my day.

So many worlds to save, so little time...

Pretty much, but I can save quite a few of them, since I'm not a heroin
addict.

Are you sure? You seem hung-up, just the same.

Don't worry. It won't seem that way tomorrow, after you've crashed.

Could someone explain this to me: From what I've seen with mobile
passive whips, even of the longer variety, the issue of resonance seems
always to be a limiting factor in band applicability.

What makes this whip suitable for such a vast frequency range (30 kHz
to 30 MHz)? Some coil or another?

How would it be any more suitable for SW than, say, the 12 foot whip
that MFJ offers?

When the antenna is at resonance it will pick up more energy from a
passing EM wave than when it is not at resonance at a receive condition.

On transmit it will not radiate as well either but worse is the fact
that the transmit energy reflects back at the transmitter and the finals
have to dissipate the extra energy.

For receive efficiency you want the antenna to be full size or larger
for the frequency of operation.

Whip antennas need a counterpoise to work well. For a car mounted whip
the ground return is the car body. For a roof mount its horizontal
radials. For a portable it is the circuitry in the box and maybe you
holding it.

I expect a CB base antenna would work better than this unit. A CB base
antenna would cost a lot less. You could do even better just hanging up
a horizontal wire.
