Thanks for anwering all the questions about the AP-10A, Barry!
The AP-10A coil and its hardware would be useful piece parts that
could be mixed and matched with other antenna parts, after a little
machine work making some adapters.
*** True.
Looks like the AP-10A makes an efficient fixed portable antenna, as
it was intended. I guess for those of us who want a single travel
antenna which can fullfull both mobile and portable requirements, the
stock AP-10A might not be quite as well suited.
*** Seems to work well for me. Doesn't seem to be very fussy in
tuning as long as I have my 259B along. I guess you could adapt the
AP-10A for mobile use, but I would rather use something else.
For the versatility that the MP-1 and its FT-817 bracket provides
with fixed portable, mobile, and pedestrian mobile use... I have a
hunch the MP-1 would still be my choice when packing light for a
trip... especially for rental cars and pedestrian.
*** Under those conditions, I would agree.
Speaking of "packing light"... I've recently been using the new ATX
with the 3/8-24 threads for those times when I travel with an
absolute minimum size package. Although the efficiency of the ATX is
not as good as either the MP-1 or the AP10A, I've managed to make
some Pedestrian Mobile SSB QSOs on 18MHz~21MHz with the ATX and the
FT-817. On 7, 10, 14MHz, I have only made CW contacts... SSB 5W just
doesn't cut it there with this combo. The ATX (3/8-24) using the MP-
1 mount on the FT-817 is a much more durable combination for
pedestian use than my "old" ATX BNC.
*** Interesting.
