I haven't bought any of their antennas for ham projects yet.  I've purchased
one of their VHF dipole arrays for a commercial job, but I wasn't on-site
when it was delivered, unpacked, or installed, so I didn't get to examine
it.  Most of what I've heard has been positive.  They share a lot of
similarity with Sinclair's products; I heard (maybe even here) that some of
their engineers, or maybe company founders, were ex-Sinclair employees.
They seem to be much more popular in Canada then down here in the states.

I have some of Comprod's filtering products and have been happy with those.

I've been very happy with Sinclair's dipole arrays, which is what I was
leaning toward buying, but the price is getting a little out of hand.  The
Decibel dipole arrays were a good value, too bad they quit making them for
the UHF ham split.  These antennas will all be top-mounted, and I refuse to
use fiberglass omnis for such installations, so my choices for dipole arrays
are fairly limited.  If Telewave made dipole arrays that included the mast
and internal harness I'd consider them too, but they don't.  TX-RX's dipole
arrays (made by RFI) are another option, but I haven't yet found anybody
using them, and I'm not sure I want to be the $2000 guinea pig.
