Just a thought here. If we could get a large inflatable mast, such as the
2.5 m ones used by yachties as danbouys, could we not wind a coil round the
bottom, then tape wire up the shaft and use? To collapse, deflate the item,
pop in bag or pocket and go home!
If we could find or get made, some, say, 5 m shafts we would be in business
with good sized verticals. paddling pools use 5m shafts, but in circles of
course.
A 5m shaft of diameter, sa, 3 inches, would not take too much puff to blow
up.
Thoughts or help?

Subject: [FT817] Re: More Antennas
Just for fun, I connected the ATX to my IC-756PRO. On the other
antenna socket was my 5 band vertical. On the spectrum display I
could then quickly check the difference in received signal strength
and estimate the difference in dB. The ATX was 18 to 20dB down on the
vertical. Of course, my little ATX stand had only a short feeder so
it had to be indoors with the 756PRO. That might have affected the
signal strength a bit. Nevertheless it is perhaps not so surprising
that it is hard to work DX. With the 5W out from the FT-817, it is a
bit like running 100 - 200mW on the vertical. Of course, you may not
need more power than that to make the QSO if only the DX station
could hear you call in the first place.
