Wire gauge only becomes an issue in transmitting applications, where currents are vastly greater than receiving, Just a belated note; willing to improve loop pattern balance and have deeper null, modify the thranformer by adding a center tap (at 2 turns) on the antenna side and connect the braid to this tap instead of connecting it to the other winding. The primary and secondary are identical, therefore as long as the respective ends are not crossed, that is, one end of the primary and the other end of the secondary connected to the inner conductors for example, all is fine. The ALA100 is a good amp, but was it designed to operate with such a small loop? You can also probably use anything larger, so long as it fits. Antennas. I hope to compare use on the RF-noisy porch vs the RF-quiet field. > “An NCPL loop will not perform well with most other receivers, though–they simply don’t have the dynamic range to pull it off.”. “The second characteristic of this loop antenna is that it is a high impedance loop, which might appear counterintuitive. RG62 is 93 ohm cable once used for ARCNET networking in the 80’s. “Preliminary testing shows a clear advantage to passive antennas, such as folded dipole and rabbit-ear types, over low-cost active antennas… A suggestion for an external AM and FM active or passive antenna; and . Any reason the Balun can’t be built on a toroid or a single tubular core? Our BALUN has typically 0.28 dB loss. Empirically I find a good linearity up to 25 MHz. Another length of cable terminated on one end with a connector of your choiceas a feed line Type. It should look like this: Don’t have a binocular ferrite core like the one above? Signal (gain) enhancement is probably the most typical use of passive loops. Write a review. […]If you want to boost the performance in VLF, LW and MW, you can try a different impedance ratio, but this will kill the higher bands.”. Passive antennas contain radiating element only such as ceramic patch or helix structure. Next, create the cross-over point of the loop by simply attaching the center conductor of one end of the cable to the shielding on the other end…and vice versa. I could not believe how great it works. I’ve supported it a number of times with fishing line/filament from two sides (tying on at 10 and 2 o’clock on the loop). I suggest taking a closer look at the circuit as built vs the circuit as presented, and maybe drawing both out yourself. Next, attach the other end of the balun leads to each portion of the center conductor, as seen below: Update: Note in the loop diagram near the top of the page that the ground wire on the output connector connects to the loop coax shielding on the primary side of the balun.
