|First light for the Booster (hi)|
I built the Booster to experiment with larger cylinders and a larger coil to work on 14 MHz and 7 MHz.
The Booster has twice the size of the Red Bull antenna.
The length of each cylinders is 22 cm. The wing span of the dipole is 22 inches. The coil former has a diameter of 110 mm and the coil has 15 turns. The taps are two turns apart.
The Booster resonates just above 10 MHz.
Giving CQ on 40 m with just less than 3 W on the Booster, resulted in contest QSO's with DL (1), HA (1), OE (1), OK (4), SM (1) and UA (3)
