[IRCA] Major PVC Loop Article Uploaded to DXer.Ca & Ultralightdx

[D1028Gary@xxxxxxx]

Hello All,
 
During the spring and summer, serious experimentation into large  
PVC-framed tuned passive loops (of up to 9 feet per side) was  undertaken here, which 
included the actual building of ten different loops--  with sizes ranging 
from 18" to 9' per side
 
Finding PVC to be an ideal, lightweight frame material which offered great  
structural strength (if the proper PVC diameter was used), I was fascinated 
with  the cost-to-performance ratio of these inexpensive loops-- even to 
the  point of writing a full construction article suitable for building any 
one  of the ten sizes (they all use a standard frame design). This major PVC  
Loop article has just been uploaded to the "ULR Antenna" section of the ULR  
File area on _http://www.dxer.ca_ (http://www.dxer.ca) , and to the  
Antenna section of the Library File of the Ultralightdx Yahoo  site.
 
Prepared with major assistance from John Bryant and Steve  Ratzlaff, the 
article includes full pipe size, wire length, coil turn,  weight, cost, and 
frequency coverage information for nine different  Medium-Wave loops-- of 
18.5", 25.5", 40", 48", 63", 66", 75", 91" and 109"  per side, as well as a 
Longwave model of 77" per side. All of the  Medium-Wave loops can be built for 
under $55 in total cost, and none of them  weighs more than 16 pounds-- even 
the monster 9' sided model.
 
It is hoped that this fascinating experimentation will give a boost  in 
DXing fun to users of both Ultralight and table receivers, and open  up an 
exciting new world of weak-signal DXing to hobbyists in both  groups.
