I am using the generic Metra harness that has two plugs. On the 10 pin plug, there is a blue wire that is looped to connect to both Pin 9 (red/black) and Pin 8 (violet) and there was a longer wire also coming out of Pin 9 that was marked "Power Antenna". Thinking the loop back was the problem, I cut the loop wire, and left the power antenna on ...
players, LCD and Plasma TVs, set top boxes and the like, as the majority all use switch mode power supplies. Keep the loop as close as possible to the radio. Say within 30mm. Keep mobile phones away from the loop. First tune the frequency of interest then tune the loop for best reception.
A loop antenna is a radio antenna consisting of a loop or coil of wire, tubing, or other electrical conductor usually fed by a balanced source or feeding a balanced load. Within this physical description there are two distinct antenna types: The large self-resonant loop antenna has a circumference close...
Sep 16, 2010 · The goal of antenna is to induce a resonance in the elements. This is why most antennas you see are some nice fraction of the wavelength; the peak of the radio signal helps reinforce the wave already moving in the antenna. This has the effect of having a nice change in impedance between the air and the antenna for the incoming wave.
Jun 05, 2013 · Using its 831-foot Blaw-Knox antenna to broadcast at ten times the power of any station, it earned the title 'The Nation's Station'. Locals reported hearing broadcasts on barbed wire fences, milking machines, rainspouts, water faucets, and radiators.

Has BNC connector for transmitter, two wing nut posts for loop wire connections, tuning/matching capacitors.
The ferrite rod antenna cannot handle any power without the ferrite saturating. Ivan's post with the pictures of the receiver show what can be achieved if the loop can be hidden, or made more acceptable. I once tried to stuff about 8 Watts into a loop-stick antenna at 1.4MHz. The ferrite got hot and the VSWR was way out.
