MY BIG VERTICAL ANTENNA PROJECT - K8JHR.com
www.k8jhr.comI do not believe I can raise a wire dipole antenna higher than 40 feet at present - at least not without installing a tower or some other tall support structure in the yard or on the roof of my home. Therefore, I decided to erect a large vertical mono pole antenna after considering NEC charts and related
The Beverage Antenna, 100 Years Later
www.arrl.orgThe Beverage antenna has a characteristic impedance and not a feed-point impedance. Like a dipole antenna, current in the Beverage’s horizontal wire creates an electrical reflection or image on the ground below it. The current in the wire and its image create an unbalanced transmission line with a characteristic impedance. If this

One difficulty is finding a point source, since any antenna, even a half-wave dipole at 10 GHz, is much bigger than a point. Even if we were able to find a point source, it would radiate equally in all directions, so the energy that was not radiated
The Basics of Patch Antennas, Updated - Orban Microwave
orbanmicrowave.coman antenna relative to a dipole, we use dB d. No antenna losses have been included so far and the integrated average of the directivity pattern over an entire sphere has to be 0 dBi. This implies that creating directivity in a certain direction reduces directivity in other directions. Antenna Gain

Connecting Your Receiver to the Antenna
www.dxing.comConnecting to Two- and Three-Terminal Antenna Inputs Figure 5 shows three schemes for connecting the antenna feedline to screw-type input receivers. In Fig. 5A, the receiver has only two antenna terminals, one for the antenna (A1) and the other for the ground or earth (G). If a single wire downlead is used, then it is
