How does a double bazooka antenna work?
The Double Bazooka Dipole is a very efficient single band antenna which is very quiet, and does not require the use of a balun. This antenna consists of coax (RG58) or other 50 ohm type with the shield split at the center and the feedline attached to the open ends. Do not break the center conductor.
How long is a double bazooka antenna?
10M – 16′ ft.
A double bazooka beats a dipole in bandwidth and performance any day. Approx. ​Length : 10M – 16′ ft.
What is a fan dipole?
Full-Size Fan dipoles are multi dipoles that are fed with a common feed point. The full-size dipoles are spread out like a fan, hence the name Fan Dipole. A good example of a Full-Size Fan Dipole is a full-size 40- and a full-size 80-meter dipole on a common feed.
How does a NVIS antenna work?
NVIS only works at frequencies from 2 MHz to 10 MHz. The signal must penetrate the D layer of the ionosphere, and bounce off the F layer. Lower-frequency signals will not penetrate the D layer; higher frequencies will not bounce off the F layer at these sharp angles and just goes out into space.
What is a double bazooka?
A DOUBLE BAZOOKA antenna is an extremely broad banded Half Wave Antenna which can operate efficiently across an entire Ham band with little change to the SWR. The BAZOOKA antenna design was developed by the staff of M.I.T. in the early 1940’s for use by the US. Government as a radar antenna.
Can a make a dipole antenna?
It is easy to construct a dipole. Basically it is simply a half-wave length of wire cut in the middle. Egg insulators have the advantage that if they do fracture for any reason they will fall away, but the wire and securing rope will still be looped around each other, meaning that the antenna will not collapse.
What bands go with fan dipole?
The Fan dipole for 40/20/6m performs well. Now it’s time to extend the Fan with more bands….First attempt.
Band | Length approximate (one leg) | Remark |
---|---|---|
80m | 20 meter | support wire |
15m | 3,7 meter | |
40m | 10 meter | |
10m | 2,5 meter |
