Antenna Calculator
The measurements below are for building a simple Dipole Antenna. The Wire Size can range from 16 AWG to 12 AWG. The larger the wire, the wider the bandwidth

end-fed half-wave antenna for the 7 or 10 mhz amateur bands for portable qrp
FLAT EH antenna band 10 MHZ
Much of the low band HF is full of clicks and other strange noises. I began to listen to 10 MHz and found lots of activity and interesting stuff to listen to. At that time I used a 42 metre long wire fed into an ICOM AT-180 tuner and my transceiver was an of ICOM-7000. Although I had not had many QSOs on this band I was intrigued and quickly decided to construct a quick and easy flat EH design, not the EH cylinder design

This was a very frustrating antenna to tune and install

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane

Calculo da Antena Bazooka A double bazooka antenna is a combination that has a complete coaxial wave multiplied by its velocity factor and a total end-to-end length of 1/4 wave for each side affected by another driver shortening factor
