Are there any commercially available skew planar or ?cloverleaf? antennas
available for 2 Meters/432? These have become commonplace for drone
operations at 2.4 and 5.8 GHz because they offer circular polarization. This
makes control of the aircraft more reliable as it moves through space with
changing antenna orientation. Previously, omnidirectional antennas similar
to our ?rubber ducks? were the norm.
Skew planar antennas seem to offer a good option for satellite operations,
especially portable. But availability is always an issue.

The in-depth construction link on that page is dead. He's a link to the
archived page, but, sadly, the photos were not archived.

Rich, my last location was worse than yours I believe. I lived in an large
city two story home with 9' ceilings and a large peak roof, think 1903
style. There was a three story home on the east side and a three story
church on the west. Three very large oak trees in the front and very poor
aim points to the north. I mounted my tripod on a one story wood shed on
the north end of the home. I had about a 60' run of hardline to the shack
and used high gain yagi antennas for vhf/uhf. This setup worked fantasy and
always was amazing to me. I even pre purchased a Super-Amp SP-7000 for UHF
but never found that I needed it. Use some antennas with some gain and I'll
bet you'll be just fine mounting on the garage or lower build.

Thanks. I've gotten a number of responses ranging from:
Put up a tower
Put it in the attic
Put it on a tripod on the roof
And - yours - put it somewhere reasonable and don't freak out about the
attenuation.
The garage and the house both have 8/12 pitch roofs, so that's my concern
with mounting on the roof. I've done it before but I'm happy about it.
The garage is lower, so less of a fall, but still steep.
I might be able to get a small AZ/EL setup inside the attic above the
garage. The issue there is my shack is on the exact opposite side of the
house. So, I'd most likely need to move the shack to the garage attic.
There's power up there, but no insulation. Maybe I could put the IC-9700
there and remotely control it?
I've thought about a tower... But there are so many tower options, it's a
little daunting. If I put the tower just outside where the shack is, I'd
need about 38' to clear the highest peak of the house roof. I could go
lower and just live with a little extra attenuation from the house roof.
And I assume any tower would come with the need to deal with the local
zoning/permit guys. If I go that route, I'd want the tower to be high
enough to use as the center of a dipole also.
Too many options...

The Olde Antenna Lab may still make those to order.? Those were his

Trying to grasp how these would be especially advantageous to portable
satellite ops. Actually, I?m trying to grasp how omni antennas would be
advantageous for satellite ops in any form outside of telemetry collection
where you don?t want to have additional wear on a rotor you use for making
contacts.

Easier to set up for the newbie, who may not want to put up a rotator
right off the bat. Sure, performance suffers without directional gain,
but life is a series of tradeoffs.
I have two 2m antennas which aren't movable and have little/no
directional gain (copper pipe J-pole and copper pipe folded horizontal
dipole). Both can easily hear the FM and linear sats, even after 50' of
RG-8X.
However, based on the elevation plot, I'm not too sure that this antenna
would be useful. They have gain below the horizon that would better be
used above 0 degrees. Hard to hear a satellite through miles and miles
of dirt. :-)
Or, perhaps I'm interpreting Figure 1 wrong on [1].

I use a fiberglass mast by MGS for my M2 LEO antennas and G5500 rotator.
Works fine.
You may not have enough room for the guy lines? I have expired HOA
covenants, the best kind!
Mine is up about 30-35 feet. PM me for details if you're interested.

Rich, the attic has always seemed like an attractive location to me, but
I'd suggest before you go that route, do some reception checking. For
example, see how well you receive one of the Foxes on an HT on the ground
outside, and then go to the attic and see how similar it is.
For reasons unknown, the last time I tried this I was totally unable to get
ANYTHING in the attic, although I know some people have done well there..
I wonder if it relates to the spacing of the nails compared to the
wavelength, or something about the particular mixture of material used in
the shingles?

Many newer houses have foil backed plywood decking to block heat transfer.
That also blocks rf.
