| Monster Cylinder Dipole PA1B |
Mønster Cylinder Dipole in the CQ WW WPX 2015. (Click on the picture to enlarge)
The monster antenna consist of two
Mønster Energy Drink Cans
and a coil of 80 mm with 8 turns.
I determined the number of turns of the coil by experimenting.
This very short antenna has a wingspan of 15" or 38cm. "Indoor" results are best if you place the antenna as high as possible.
By making QSO's in a major contest, I could discover the properties of this very short antenna. All QSO's are made with CW and with S&P (Search and Pounce). As a low power enthusiast, I will reduce my power when the received signals get stronger.
On Saturday I worked with the Monster Dipole in the shack, on a height of 4 meters above the ground. On Sunday morning I placed the antenna in the dormer window in the attic, on a height of 7 meters above the ground.
Saturday
On Saturday I started on 14 MHz. Between QSO #3 and #4 we went to a fair. After working 6 stations all on 14 MHz, I went to 21 MHz.
The 15 meter band was open, so I made all QSO's on this band from 12 UTC until 19 UTC. From time to time I went back to 14 MHz, but with NO success. After 19 UTC I could make just one QSO on 20 mtrs. After this QSO an other 16 QSO's were made on 15 m.
After 19 UTC the signal were stronger, so I could reduce my power. I could make QRPp QSO's with 720 mW, 360 mW and even one QSO with 72 mW.
Miles per Watt
As a low power enthusiast, I reduce my power before answering a CQ, when the S-meter goes up.
It was great fun to make a QSO with 72 mW with YT6A, over a distance of 851 miles.
This QSO is good for 11820 Miles per Watt.
Thanks to Ranko with his sensitive station with Excellent Ears. FB.
Sunday
On Sunday morning I had time until 10 UTC. The first QSO was made with the Island of Man on 7 MHz. To work on 7 MHz I tune the SWR for 1:1. After breakfast I decided to move the Monster Cylinder Dipole to the attic, just to test whether I could make more QSO's on 14 MHz.The test is not conclusive, because I made the same number of QSO's at the same time as on Saturday.
Between 10 and 18 UTC we visited two birthdays. after 18 UTC I made a few QSO's.
Does it work?
The Cylinder Dipole definitely works.
Because I had limited time on Sunday afternoon, I can not tell whether the antenna works better on the attic on 14 MHz. But I can tell you that it works.
In the interesting table below I show the QSO's from hour to hour.
Please notice the peak in the propagation on Saterday from 19-21 UTC.
I worked 7 stations with 360 mW. But that was not all.
I am very pleased with results of the Monster Dipole.
When did you make QRP QSO's with 20 DXCC counties on a indoor antenna with a wingspan of 38 cm or 15 inch? Hi.

The QSO with 72 mW is years later, still the QSO with the lowest power on the Monster Dipole. Hi.
I am very pleased with results of the Monster Dipole.
