My old dipole was also constructed with the 16 AWG heater wire and may have been a touch too long. It was not as carefully constructed as the bazooka antenna. It was very close though. The feedline hasn't changed except for the 2 inches lost when cutting the old antenna off. Height is about 2 feet lower for the Bazooka, and between 35 and 40 feet up.
Orientation remains identical.
The new antenna is stretched a little tighter though. This is a neat antenna and I can tune up the rig without a tuner on the entire 40 meter band. The drake loaded well into the Bazooka. I am using my tuner anyway, and noticed the ant. It is a great single-band antenna, but bulkier than a dipole.
