Yea - that is curious isn't it - - I suspect that it is the same
syndrome that is affecting lots of engineers these days - engineering
to the edge of the envelope and not allowing for any slop - i.e.:if
the circut is @ 16v, then a capacitator rated at 16 v should do
it.... wrong..... I have discussed this with folks I know that work
in the tech engineering field that head engineering teams, and they
confirm this..... It drives me (& them) nuts to see that the most
common failure in a piece of equipment is in the power supply -
something that is relativly easy to engineer.
I don't have quite this bad a problem with the Maldol - I think mine
actually might be ok - but I do with the ATX, and cured it by making
a 4 spoke capacity hat out of 24 gauge solid wire and soldering it to
a mini-aligator clip.

you can't do a darned thing about it other than add an external
loading
device, or kludge up some kind of whip extension.

Subject: [FT817] Re: MALDOL whip - SWR kinda crummy?
Kinda is not even close.
I tested some Maldol whips with an MFJ259B. At that time the 40,
20
and 10 meter versions were available from my local radio dealer.
The 10m is fine, and resonates at a little less than 29meg.
The 20m will not go under 16.5 mhz even with a counterpoise.
The 40m is similarly high.
The resonant points had reasonable SWRs, just too high in
frequency in
the 40 and 20 cases.
I don't know how any of the other available bands work other than
the
3 I tested.
If someone could find a way to extend the whip a couple feet in a
way
that would be strong and light, they might work OK.
