If you look at the A-D sellsheets for the C1/C2/C4 antennas & specs for Micron-2, you'll
see that they are indeed "optimized" for the New UHF Band (470-698 MHz), with Gain
falling off (slightly) and the SWR climbing across the higher Old Band frequencies....unlike
some Full Band antennas that peak within the Old Band...
This is a small detriment on all except the higher Gain C4, which has a big SWR increase.
It just happens these new A-D antennas (except C4), ALSO perform quite well in the Old Band: http://www.antennasdirect.com/cmss_f...-sellsheet.pdf http://www.antennasdirect.com/micron-2-gain.html

Convert ClearStream2 for VHF-HI?
Is there any way that I can convert my ClearStream2 so it can also receive VHF high? I see on Antennas Direct website that they now have a Clearstream2 "complete" that does. If I can do something to my existing CS2 to do the same thing, it would CHCH to me and let me keep CFTO when they convert. If it is possible, please respond in plain English as I am no techno geek!
A piece of 36" wide 2"x4" wire mesh attached to the reflector should help with VHF. 35"-36" aluminum reflector rods will also work.
It may also help to attach an extra element at the connection point. Whiskers, probably in the 13" to 16" range, may work. 20"-22" loops may also work. Not sure what length will work best. The whiskers and loops would need to be modeled for performance.
Hmmm - was considering the Clearstream2, but had a few concerns about VHF-HI and CFTO or CHCH. Would be waiting until after post transition anyways, but am wondering if it would be better to wait for the Clearstream2-V. Any idea when it may be available in Canada? My little unamplified Terk does very well considering what it is, but I wouldn't mind being able to get some of the US channels a bit more reliably.
That's lot of metal and work... A simple dipole and UVSJ with some hardware works pretty darned well for basic bi-directional reception of high-VHF. If you need directivity or higher gain, you'll have to look at larger antennas that includes a reflector and, possibly, directors. At least now we have a modest-range 7-51 antenna solution that is properly predictable.
No idea when they might be available in Canada. It's up to our Canadian retail partners to order them. We've only had them in inventory for less than two weeks and they've been available on the website for less than that.
PS. A mod might want to move this into the thread that specifically discusses our products.
