Sirio Boomerang 27A as a HF Antenna?
A QRP operator is supposed to compensate lack of power by using efficient antennas. But what if efficient antennas are not practical? At my QTH, I cannot put huge antennas up due to lack of real estate. I tried a Diamond CP6 but sold it to a friend after the overwhelming size and venerability to the wind, especially when I was out of town, I was always worrying when it got a little windy.
So, I have thus far been using just a 25M end-fed longwire, but I was missing the local 10M club net, so I found an old Sirio Boomerang 27A and put it up. It worked a treat on 10 meters, but trying it on other bands with my LDG Z-817 Tuner seemed to be acceptable all the way down to 40M. It is especially “sweet” on 20M and 17M. I have made contacts into the USA, Cuba and all over Europe. I hope that others will try this remarkable antenna. I tried to go one better using a half wave CB antenna and it didn’t come close to the performance of this quarter wave – perhaps its some matching circuit in the Boomerang – whatever it is, its the perfect small HF vertical.
