Cushcraft, MFJ, Hy-Gain, and Jetstream all make dualband yagis with both
bands having the same polarization. Cushcraft is a little unique in that
the elements for one band are on the top of the boom, and the elements for
the other band are on the bottom side of the boom. Both bands have driven
elements that are coax fed and there is a coax harness with a T connector
and short runs of RG-58 which does to the feedpoint for each driven element.
The other brands use elements that go through the boom, and they are
interspaced with each other on the boom. I know Jetstream only has the
coax attached to the 2 meter driven element, and I think it couples to the
70cm driven element through their harmonic relationship. I think Hy-Gain
and MFJ do the same thing, but I am not positive on those, as I haven't
looked at their manuals recently.
I have the Cushcraft A270-10s which has 5 elements on each band on a 6 foot
boom. I have the 2 meter elements on the bottom side of the boom, and the
70cm elements on the top of the boom. The band which is on the bottom of
the boom seems to have a pretty normal pattern. The band which is on the
top of the boom seems to have its pattern skewed where the main elevation
lobes are at a pretty high angle. On Mode J satellites I don't hear the
satellite very well unless it is a rather high pass, and I don't hear it
well during the beginning or end of the pass. SO50 is rather hard to hear
at all, AO51, AO27, and FO29 are/were easier to hear, but it still shows
the same type of pattern, you don't hear much until you get above 25 to 30
degrees of elevation. The Mode B satellites exhibit a much more normal
pattern-I can hear the XW2 and CAS-4 satellites throughout most of the
pass, and AO91 and AO92 through most of the pass also, with some fading
here and there when the satellite changes polarization.
I have also owned the Jetstream dualband yagi in the past and it had pretty
impressive performance for an antenna with a 2 1/2 foot boom. Its
elevation pattern seemed to be more normal than what I get with the
Cushcraft on 70cm. The biggest problem with the Jetstream right now is
finding one. R and L electronics is out of them, Jetstream is out of them,
RW antennas on ebay is out of them also. I bought a used one on ebay and
when it arrived it was the Jetstream dualband vertical instead. They
luckily refunded my money, but they didn't have the used yagi to send me
instead. They seem pretty scarce right now, but they did perform pretty
well on the satellites.
I have not used the MFJ or Hy-Gain yagis so I cannot comment on them. The
MFJ yagi with the 4 elements on 2 meters and 7 elements on 70cm uses a
circuit board for the feedpoint. That looked a little too fragile to me
for the long term. MFJ has a newer yagi with 3 elements on 2m and 5
elements on 70cm with a different feedpoint arrangement. I think it is
pretty much a direct copy of the Hy-Gain dualband yagi, since both
companies are owned by MFJ. I cannot comment on the radiation patterns of
these antennas, but they could be similar to the Jetstream since the
elements go through the boom like they do on the Jetstream.
If we had many more satellites running Mode J I would replace the Cushcraft
with one of these others. Right now with only 2 satellites using Mode J,
and FO29 still pretty workable, I haven't bothered as I am also into 2
meter SSB and the Cushcraft is twice as long as the others in terms of boom
length so it is probably a better performer on that band. It also seems a
little more rugged than the others. The Jetstream is limited to 100 watts
and I blew out one of the driven element arrangements on 2m running 80-90
watts through it. It was under warranty so Jetstream sent me a new driven
element, but I still had to go up on the roof and replace it, something
that might be hard to do depending on one's setup.
For a portable hand held yagi I think the Jetstream would work very
nicely. It is light, doesn't need a duplexer, will handle 50 watts from a
FT100/FT857/FT991/FT897/Icom 706MKIIG type of radio, and the elements are
attached with wingnuts which can be broken down very easily for transport.

Doug,
I been thinking about this as well.? One antenna (arrow) for those birds
with antennas at 90 (SO-50), and
another for those birds with them in line. I've been looking at parallel
designs(think "trident") e.g. take my elk, use that for 2m, and have a
clip-on parallel spot for a 432 or 1.2G beam.
Tired of doing the TX-90-degree-twist.

Doug,
The problem, as I see it, is that 2m and 70cm are harmonically related.? If
the two Yagis were in the same plane, there would be more interaction
between them.? Placing them 90 degrees apart minimizes such interaction.

I've built cheap yagi's with the 2m/70cm elements on the same plane (
http://www.druidnetworks.com/same-plane-cheap-yagi.jpg) and used them to
work down to the horizon on all the FM birds - from a clear location of
course. Check out the AMSAT facebook page from about a year ago, and my
youtube channel for the videos if you're super interested.
According to WA5VJB's ubiquitous document (
http://www.wa5vjb.com/references/Cheap%20Antennas-LEOs.pdf) the plane
alignment shouldn't matter so long as the elements aren't interacting with
each other. He's a much smarter cat than me, and after building such gizmos
based on his design, I have no reason to believe an arrow built in the same
fashion wouldn't also do the trick.

Forgot to add - I've also built several 'sleeve driven' designs in my early
days, and they only performed at a fraction as well as a proper driven for
each band. If you're more interested in just straight up ease of
construction without requiring a duplexer or 2 rigs, then it's certainly an
option. But if you care about hearing the bird < 15? then you'll get
superior performance using a individual band driven design.

> before you send a command to one of the VFOs (set/read frequency and mode,
Ctcss-tone etc.) you have to send a command that speciefies the VFO to which
the following command(s) will be sent. The specified VFO will automatically
accept VHF, UHF and L frequencies (if you have that module). The command
and sub command bytes for the IC-910H in non-satellite mode are: VFO A: 07
00, VFO B: 07 01. Satellite mode Main VFO: 07 D0, Sub VFO: 07 D1. Of course,
you need to send always the complete command string incl. header and FD as
terminator, see manual p. 78/79.

already: You don't need to switch anything manually.

of my rig, an Icom IC-910H without the L band module. After a few struggles
with the manual being either wrong or missing information I?ve run into what
could be a potential problem later. When using command 0x00 to set the
frequency, the rig will not switch bands on its own. Whether this makes
sense or not is debatable and I have a couple possible workarounds, some
uglier than others. I can either read the bands that Main and Sub are on and
send my 2m and 70cm frequency to the correct place (elegant) or I can send
them both the same frequencies and let the rig sort it out (ugly). Now comes
the tricky part. I don?t have the L band module yet but when I do, how am I
supposed to get the rig to switch from say L/v to U/v if it doesn?t auto
switch bands?

there is an undocumented command or some other type of workaround? I would
also be curious what users of SatPC32 experience when they switch between
L/v and U/v. Do you manually have to switch bands to regain frequency
control or does the IC-910 become smart enough to switch on its own when the
module is installed?
