Construction is in the early stages. Future posts will show the progress of the construction. The 6mm-diameter pipes used are shown below. Here are the 90-degree corner pipes, bent by hand. An idea about the capacitor mounting is shown. Magnetic loop HF antenna In the past I experimented with an HF magnetic loop antenna for the first time. These antennas are well known and work well, but for some reason I'd never used one apart from on 136 and 500kHz where I used an 80m square magnetic loop made from standard PVC covered wire With QRP at this time in the solar cycle you need every advantage you can get to be heard. IMHO, a magnetic loop antenna is not an advantage! That said, if that's all you can get away with due to restrictions, give it a try. But an end fed longwire up in a tree is about as simple and cheap as you can get, and can be quite efficient and stealthy. Eine magnetische Loop Antenne für Kurzwelle ist besonders gut für Innenräume geeignet, da sie völlig unempfindlich gegenüber elektrischen Störungen ist (Netzteile, Wlan, Handy, Smartphone, Lampen, Computer, Monitore etc.). Sie funktioniert gut für Kurzwelle ab 3500 khz und ist gegenüber kommerziellen Loopantennen mit ca. 25 Euro Kosten sehr preiswert. Du brauchst lediglich 2 Meter.

Even at 100W, I was on par with an 80M skyloop from UT to SC on 20M, but the mag loop had a much better S/N ratio. I am setting up 2 loops here in Vegas. 1- 80/40M & 1- 20/10M Both will be controlled by the unit above (Latest firmware has a freq cutoff to switch a relay & control 2 loops) The magnetic loop design leads to antenna which is tuned to a very narrow frequency range, giving good selectivity. However, it also requires retuning quite often in order to stay on-band. [Eric] is implementing a self-tuning system to solve this, with a controller using a motor to actuate the tuning capacitor to maintain the antenna at its proper operating point. If you're unfamiliar with. Performance of magnetic loops this size have been extensively analyzed and reviewed. Mine is no different than the others. Please do not expect miracles! Ultra-Portable QRP is hard stuff and you will need to rely the 3 P's: Propagation, Perseverance, Patience. In a nutshell this loop performs at around the same level of full sized half-wave dipoles or of a vertical antennas. Yet, you are.

zA magnetic loop behaves electrically as a coil (inductor) with a small but non-negligible radiation resistance due to its finite size. It can be analyzed as coupling directly to the magnetic field (opposite to the principle of a Hertzian dipole which couples directly to the electric field) in the near field, which itself is coupled to an electromagnetic wave in the far field through the. The magnetic loop consists of a conductive loop that is separated at one end by a capacitor, thus forming an LC circuit that has to resonate at the operating frequency of the antenna. A smaller loop is positioned towards the opposite end of the capacitor within the area of the main larger loop. This smaller loop is connected to the transceiver via an impedance-matched feed line. Both small and.

Magnetic Loop - Reste-Antenn

Powered through the construction of the magnetic loop antenna for HF last night after a last run to Home Depot for supplies. I had purchased three different capacitors from Ebay for this. One was unsuitable due to voltage handling. One was great for voltage handling but a bit bulky and stiff to turn. The one I decided to go with has a capacitance range of about 10pF to 110pF when both halves. Magnetic loops can be fed in a number of ways - coupling loops, gamma feed, toroidal coupling and capacitive coupling. I decided to give capacitive coupling a go following the ideas of DG2IAQ. This is also known as Army Loop or Paterson coupling. You simply feed the loop directly across half the capacitor with a series capacitor to match the predominantly inductive load. The series.
