Cylinder dipole in CQ magazine

Cylinder dipole in
CQ Magazine

In the CQ WW WPX CW contest 2016 I used two indoor cylinder dipoles. After I sent in my log for the CQ WPX, Terry N4TZ noticed my soapbox. Terry asked my to send in a picture of my cylinder dipole to include in the write up of CQ Magazine. I thank Terry for the nice and beautiful write up.

The CQ WW contests generate a lot of activity.
I use contests to make QSO's with very low power.
And. . it is good opportunity to test your antennas.


Soapbox PA1B in CQ WW WPX CW 2016
X-RADIOS:           FT-817
X-ANTENNAS:    Cylinder dipole
SOAPBOX:            I had great fun with QRP and two cylinder dipoles
SOAPBOX:           On 20m I made 3 QSO's and on 15m 4 QSO's with a 15" cylinder dipole 
SOAPBOX:           On 40m I made 3 QSO's with a 22" cylinder dipole 
SOAPBOX:           The PA1B cylinder dipole consists of two cylinders and a coil
SOAPBOX:           The coil acts as a impedance transformer
SOAPBOX:           The QSB and the good activity, did not make it easy to answer CQ's - hi
SOAPBOX:           Thanks for the activity in the contest

PA1B with cylinder dipole in CQ Magazine

The cylinder dipole shows a large capacity between the cylinders.
Although the coil and the capacity  are tuned to the band of interest, the cylinder dipole can be used as a multi-band antenna. Two taps at the center of the coil provide a low impedance feeding point to connect the twin lead.  Match for a SWR of 1:1 with your symmetrical tuner.

  Energy  Booster  cans or not, a cylinder dipole will radiate better than a wire dipole of the same length.

Thank you, Terry for the very nice write up.
