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.
