Re: [IRCA] Guy Atkins compares some 21st Century antennas.

Patrick, Kaz (and all),

The FSL antennas were never designed to compete with large, single-loop wire antennas in wide open spaces. Their unique advantage is the ability to provide high-gain, low noise transoceanic reception with a "footprint" of only one cubic yard. No single-loop wire antennas can match them in that aspect.  

In the special environment of sheer ocean side cliffs, the FSL's apparently tap into a previously unknown cliff-side transoceanic propagation boost, which can boost their performance up to astonishing levels. Last year at both Cape Perpetua (near Yachats, OR) and at "Rockwork" (near Cannon Beach, OR), an 8" FSL was providing S/N pegging reception of 2.5 kW New Zealand stations on a PL-380 Ultralight radio. This setup was used to provide reception of 5 DU's that were not in the Grayland Master Log-- mostly at very strong levels. At the sheer ocean side cliffs, the FSL's also receive some measure of back-side signal rejection, due to the solid rock surfaces (which were blasted out by dynamite). All of the traditional DXpedition antennas will not fit at these special sites, which is why there is currently intense interest in FSL antenna experimentation.

So true, KAZ! Unfortunately you won't be able to fit your usual antenna(s)
of choice on the Cape Perpetua cliff when you join us in July  :^)

It would be very interesting though to compare a FSL when DXing at the
cliff to a small single turn car-top loop like Mark Connelly's "Super Micro
Loop".  To my knowledge, the West Coast DXers I know have never tried
something like that. I've never seen one on our DXpeditions anyway. We
usually have room for at least a phased array of ALA100 deltas or Flags.
