Re: [IRCA] Michigan DUs, Sept.22, 2018



Bruce Conti might be the one to ask about comparisons, but I don't know if he's on the list.

We used both a Beverage and a DKaz in 2016 when I was at PEI, but I don't recall any formal comparisons being made. The Beverage initially had some noise ingress problems, so the DKaz was used more at first. I don't recall the DKaz being particularly deaf on the low band, but then TA's in PEI are a bit beefier than TPs on the west coast.

Walt Salmaniw. was there also, perhaps he has better recollection. And, of course, there may well be files tucked away somewhere also.

best wishes,

Nick

Ditto for me. Below 900 kHz, I've never been anywhere near happy with a 160' DKAZ. That is evident with stand alone DKAZ'es and In direct comparisons with Beverages, there was no contest at all.


I wonder if the PEI group has done a comparison?

Nick,

For low band DUs like this, my phased BOGs work best.  They are aimed
roughly towards the northeast.  Phasing of course allows me to reverse the
direction and steer them towards the southwest, which I do for these DU
catches.  The DKAZ, when switched to the North, shows no trace of these
signals during A/B comparisons.  When I switch the DKAZ to the South, I may
see just the faintest carrier (if anything at all).

The situation is usually different at the top of the band.  The North DKAZ
is generally better than the BOGs when pulling in 4QD on 1548 and the low
powered Aussies on the X-band during those rare times that propagation is
good here.  Point being, it's good to have multiple antenna options!

73,
-Tim
