[Elecraft] The Junk Box Special Antenna data

[Michael D. Heit KD7YLA]

I built what I call my "Junk Box Special" antenna...cuz that's where all 
the parts came from!  I used PVC tubing left over from my last effort at 
home plumbing ... tow Radio Shack folding antennas and some coax. I 
wound six turns of coax around one end of the pipe and wired the two 
radials in the center fed dipole configuration. Here is the data I saw 
using my K2 ATU in auto tune mode:

BAND/MHz                SWR
80M / 3500                   7.1:1
40M / 7000                   8.1:1
30M / 10000                 5.8:1
20M / 14000                 1.1:1
17M / 18000                 1.2:1
15M / 21000                 1.1:1
12M / 24800                 1.8:1
10M / 28000                 3.5:1

Well ... it's kinda limited, and I haven't yet tried it on the air with 
contacts ... but the price was right and it took about one hour to throw 
it all together .... I think the actual go buy the parts cost would be 
less than $10.00, it's very light and portable. Next project, go up on 
the roof and set a trip wire for Santa Klaus ...er ......
a center fed dipole of about 50 foot length .....
