To All from PA0SE 1) When you state that the Radiation Resistance of a loop antenna is proportional to the square of its Area, you are of course quoting the accepted formula, but you will remember th
The type of capacitor to be recommended for matching loops is the Philips 386 polypropylene series. Readily available in Europe in 10/22/47 values from 1nF to 100nF and above in 1kV and 2kV ratings.
Bill A sed-- For those that are this crazy, the loop conductor will have to use #6 or multiple runs of smaller size wire and the capacitor will have to be...... well, something exotic! The 'Crazy' I
Mal, From Dave G3YMC I notice this series resistance figure was not given in G3KEV's recent mail, it is by far the most important characteristic of a transmitting loop. What's the story, here? The wo
Rick, You are absolutely correct with your 3db increase for a doubling of the area. I didn't account for the doubling of the Rac in the conductor. The loss ground loss may increase in proportion to t
Hello Bill, So based on that a 10m high and 100m long loop should perform as well 32m high square loop. Doubling the length of a long&low loop should increase the radiation resistance by 4 and the lo
Hi Rik, What really looks interesting for a loop installation, according to the math, is the effective power gain that can be achieved by stretching the horizontal dimension. On my property I can mak
Hello Bill, I following the discussion on loop antennas with great interest. I'm far from a specialist, but trying to learn ... What really looks interesting for a loop installation, according to the
Hi Dave, The main problem with transmitting loops is the enourmous current and Voltage which is generated when exciting them with decent power. It's all very well to put 1W into a loop but try 1kW an
