Current TX antenna: 35 ft +/- downspout with 4:1 unun at feedpoint. Plenty of radials. It is working very well. With this antenna I finally achieved DXCC, WAS, WAC and WPX. Not bad for a no antenna zone. My Secret… To use a seperate receiving antenna. Downspout is noisy otherwise so it is a necessity to have something else to hear that weak DX.
Protects active antennas, pre-amps or other situations requiring a dc (or ac) voltage on the center conductor. The dc and RF paths (the RF is dc-blocked) are separated, individually protected, and recombined. The bias-T models are for injecting the dc onto the center conductor or picking off the dc to feed a powered device. DC Power Protectors

8 Antennas In Chapter 6 we found that electromagnetic waves can propagate in free space, and in Chapter 7 we saw that they can be guided incircuits. Now we need to make the important connection between these descriptions: how do electrons in a circuit excite waves in free space, and vice versa? This is the essential job of an antenna.

8 Antenna gain (G) Because an antenna is a passive device, the power radiated can not be greater than the input power. The ability of an antenna to focus electro-magnetic energy is defined by its gain. Antenna gain is expressed as a ra tio of the effective radiated output power (Pout) to the input power (Pin) The gain of an antenna is a measure of power transmitted relative
Antenna Array Design Choices & Characterization White Paper Millimeter-wave bands are of increasing interest for the satellite industry and under discussion as potential 5G spectrum. Antennas for 5G applications make use of the shorter element sizes at high frequencies to incorporate a larger count of radiating elements.

The Global Positioning System (GPS), originally Navstar GPS (stylized in capital letters in its logo), is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force.
An antenna is a device to transmit and/or receive electromagnetic waves. Electromagnetic waves are often referred to as radio waves. Most antennas are resonant devices, which operate efficiently over a relatively narrow frequency band. An antenna must be tuned (matched) to the same frequency band as the radio system to which it is connected,
If you build the antenna as shown, the computer model predicts 11 dBi gain and a front-to-back ratio of 20 dB. ARRL Lab measurements confirmed the computer-predicted antenna pattern. You may wish to read further about tuning adjustments in The ARRL Handbook. It describes how to check the antenna with a field-strength meter, or by using

antenna fed by a microstrip transmission line . This UWB antenna has a structure similar to the microstrip patch antenna, it consists of three layers: the top is a radiator; the middle is a substrate with dielectric constant; the bottom is an etched ground plane. This type of antenna can easily be
However, antennas < /4 in length appear highly capacitive and become inefficient radiators. For example, the impedance of a /4 antenna is 36.6 + j0 . the impedance of a /8 antenna is 8 – j500 . To remedy this, several techniques are used to make an antenna “appear” to be /4 . Loaded antennas
EEE 171 Antenna Array Antenna Array Notes For a dipole array antenna with the arrays lined up on the x-axis, the following field pattern characteristics are valid. 1. Main-beam direction The maximum value of the array pattern factor, F(θ, φ) , occurs when kdsinθ sinφ + ψ = 0, which leads to sin θ sin φ ψ = − kd.

From this you can see that the antenna performs a very important service. The antenna is the place where alternating electric currents, which flow up a coaxial cable, are changed into radio waves that can travel through space. At the receiving end the antenna does the reverse: It changes radio waves back into electric currents. \

the target (i.e., the same antenna is used to transmit and receive). • Quasi-monostatic: the transmit and receive antennas are slightly separated but still appear to be at the same location as viewed from the target (e.g., separate transmit and receive antennas on the same aircraft). Radio Detection and Ranging TARGET TRANSMITTER (TX ... The major components of modern radar are the antenna, the tracking computer and the signal generator. The tracking computer in the modern radar does all the functions. By scheduling the appropriate antenna positions and transmitted signals as a function of time, keeps track of targets and running the display system. Fig 1. receiving antenna). Both the case and the rear panel are well-ventilated. The front case feet are solid and extensible, allowing the front of the IC-7600 to be angled upwards. The 7 softkeys at the left edge of the screen are now black, and almost flush with the panel. A triangular index mark is molded into each key; I would have liked to see these
antenna). In cases where the input could be disconnected (such as when coming from an external sensor) it's a good idea to tie the input to ground via a high value resistor (1M-10M Ω). This keeps the input at ground potential if the wire to the sensor becomes disconnected and still has high input impedance. Vout Vin RL GND
