Eagle Vision One (EV1) was a military based Commercial Satellite Imagery (CSI) capability programmed and funded by HQ AF/A2QS (Air Force ISR Innovations). It is located at Ramstein Air Base , Germany, and is staffed by intelligence personnel assigned to the 24th Intelligence Squadron (24IS).
The vertical plane is used to plot an antenna's relative field strength perpendicular to the ground (which directly affects a station's coverage area) on a polar graph. Normally, the maximum of 1.000 or 0 dB is at the side (unless there is beam tilt), which is labeled 0°, to 90° at the top and −90° at the bottom.
The HB9XBG antenna is a vertical dipole antenna for short wave radio amateurs. It was developed by the Swiss radio amateur Walter Kägi, whose call sign HB9XBG is also the designation of the antenna. [1] During the test phase in 2020, HB9XBG built two vertical dipoles – one for the 20-metre amateur radio band and another for the 40-metre band.
Omnidirectional radiation patterns are produced by the simplest practical antennas, monopole and dipole antennas, consisting of one or two straight rod conductors on a common axis. Antenna gain (G) is defined as antenna efficiency (e) multiplied by antenna directivity (D) which is expressed mathematically as: G = e D {\displaystyle G=eD} .
The simplest way is mechanical beam tilt, where the antenna is physically mounted in such a manner as to lower the angle of the signal on one side. However, this also raises it on the other side, making it useful in only very limited situations. Horizontal and vertical radiation patterns, the latter with a pronounced downward beam tilt

Composite antennas are made by combining one or more simple antenna(s) either with other simple antenna(s) or with some kind of a reflecting surface formed into a screen, or curtain, or curved dish. Usually only one of the component antennas is resonant on the design frequency, and in that typical case, the feedline connects only to the ...
A transmatch (antenna tuner) is not required to use this antenna near its nominal design frequency of 14 MHz, and judicious length adjustments can sometimes include one other frequency band. All other frequencies require a transmatch. [citation needed] There are many variants of the G5RV antenna. Two variations of the G5RV design, called ZS6BKW ...
