- The transmitter employs an all-digital frequency-locked loop to directly drive a class AB power amplifier. The transmitter can alternatively use an injection-locked power oscillator for lower bit rates and power consumption.

Loop Antennas 5-1 A loop antenna is a closed-circuit antenna—that is, one in which a conductor is formed into one or more turns so its two ends are close together. Loops can be divided into two general classes, those in which both the total conductor length and the maximum linear dimension of a turn are

Similarly, an antenna placed at 12 feet, while your loop might be setting at a height of 3 feet, can see above and past obstacles. In home installations where the roof is composed of asphalt shingles, you will typically see a little more than 1 S-Unit of loss, but usually no more than 1.75 S-Units of loss.
- It’s a light magnetic loop antenna calculator that run on MS Windows, and allow to calculate capacitor values and voltage based on Loop circumference, conductor diameter, desired resonant frequency and the operating power. Works either in Standard and Metric units, and let you choose on material, and loop shape, as circular, square or octagon.
Since RF systems use decibels referenced from 1 mW, the corresponding voltage increase for every 1 mW power increase can be calculated with another form of Ohm's law: V = (PR) 0.5 = 0.223 V = 223000 µV
- 3 As it's name implies, a loopstick antenna is a magnetic loop antenna and is one of the best choices for an electrically short antenna; necessary because broadcast AM wavelengths are hundreds of meters long. Rather than a regular loop, a loopstick utilizes a large amount of (usually Litz) wire wrapped around a ferrite rod.
The "loop" part of the antenna is the inductor, and the tuning capacitor makes it resonate at a desired frequency. The schematic diagram of an AM loop antenna is shown below. It consists of an inductive winding and a tuning capacitor. The inductive winding consists of a primary, which forms a resonant network with the tuning capacitor.

Jun 17, 2013 · My interest in Maurice's work stems from my enthusiasm for small and stealthy HF antennas. As one of the pioneers of the very controversial crossed field antenna (CFA) theory, Maurice used to make and sell small loops for everything from Top Band to 6m.
