Yes. They do not have as much gain as a big wheel.73, Chris Patterson W3CMP

Subject: RE: [VHFcontesting] 222MHz Big Wheel Interest. Have you looked at the
Omniangle antennas from PAR
Electronics?http://www.parelectronics.com/omnis.phpThey also sell stacking
kitshttp://www.parelectronics.com/stacking-kits.phpI have PAR Omniangle
antennas for 6M, 2M, 220 and 432 and used all them as a rover. I have been
surprised at how well they perform. The 2M, 220 and 432 antennas are
mechanically robust. -Leandra AF1R-----Original Message-----From:

[VHFcontesting] 222MHz Big Wheel Interest.A couple of us here in Western WA
purchased BigWheels and parts direct from WiMo last year.A couple of things we
learned from that (research before and experience after receiving): First is
pay attention to customs fees. Second is that a single Big Wheel is nice but
other things do as well. Where the Big Wheel stands out is with stacking a
pair. I and another ham have stacked 2m and 70cm. The 6m model is so large
that I need to prepare space specifically for it if I were to deploy a stacked
set. Phasing harnesses aren't hard, but the one that WiMo recommended was not
correct. We couldn't understand why performance was horrible until we actually
examined the phasing harnesses we bought. They weren't correct for that
antenna and that setup. I forget the details at the moment, but we ended up
rolling our own so I'd recommend skipping WiMo's offering if you're going to
stack.So I think the bottom line is that one should get a pair of 222 Big
Wheels and stack.Speaking to Chris about the way WiMo might handle the
order(s): my guess is that they would want you to aggregate the "orders" but
that they would ship. This is what would work best and avoid any import fee
($800) The shipper would collect that and it's not part of what WiMo charges
(but they do charge for shipping.) This shouldn't be at all hard for them to
set up in their order system if they were serious about selling one. It might
be a hard sell though as 222 isn't a world wide thing so there is somewhat
limited appeal (to really just the US.)So, I'd work out with them a way that
they can take the payment and such, and you're simply a salesman for them,
trying to get at least 40 units confirmed. My gut is that even at a "new
offering" price, a pair of 222MHz would be under 800, so I'd think that finding
20 people nationwide that want a pair would be possible. I certainly would
consider it if I saw confirmed specs from WiMo (in other words, they built a
stacked set as a test and did a real world confirmation of the design.)It would
be interesting to see if someone in the US would license their design (I think
ti's a good, strong approach) and we could buy direct with no overseas
shipping, import fussing, and more simple than getting them from
