Re: [amsat-bb] 1/4 WL Phasing Line

Dave,

I believe K5OE, Jerry, may not be available.  However his homepage has a 
number of great articles on egg beaters.  He recommends for the phasing 
line:

"Finally, install the phasing/delay line. The phasing lines are made from 
RG-62 (93 Ohm, see notes below) coaxial cable. The connections from the 
coaxial cable to the loops are made using ring lugs and stainless steel 6-32 
bolts/washers/nuts. See the phasing line sketch for 
right-hand-circular-polarization connections. The 70 cm phasing line is 
5-1/2" (13.5 cm) long and the 2 meter phasing line is 16-1/2" (41.5 cm) 
long. Cut the RG-62 about 2" (5 cm) longer than these measurements and leave 
1" (2.5 cm) at each end to strip the insulation, peel back the braid, strip 
the center conductor, and attached the ring lugs. "

I hope this helps.
