I would not have expected that, and can only say that there must be others forces at work that would cause this. 50V."*/Īnother gentleman responded say the isolator made reception worse in his setup. The Line Isolator is used to bleed off antenna radiation induced common mode current on the coax braid on long (> 1/2 wavelength) coax feed lines. Note that the description of the GI300 on their website says: /*"in addition, input and output has been blocked for direct currents of max. If you install it on the side between the "injector" and the antenna the DC power to the antenna amplifier will be blocked so the antenna won't work, and you'll likely blow a fuse in the power injector, maybe even damage it. ![]() If that's the case then you install the isolator in the short coaxial cable that connects the "power injector" to your radio. I assume that means you want to use it with an active antenna that injects power into the coaxial cable to power an amplifier at the antenna. You mentioned which side of an interface it should be installed on. If the isolator seems to work a little then possible the noise is being picked up by your antenna and the coaxial cable. The IsoBeam is an isolator radome that is available as an optional accessory. If the noise is being picked up by your antenna then the isolator will do nothing because, as far as your antenna is concerned, the noise is a legitimate signal. Add to cart On sale Palstar Vernier Drives BT1500A and Tuners. Palstar Bulb set Last items in stock 18.00. The transformer breaks the shield at that point so the noise can travel no further. Add to cart On sale Palstar Replacement Bulb Set. The isolators provided a great deal of isolation for noise that is carried on the coaxial cable shield. However, this didn't bother us at the time because we were after European LW broadcasters and non-directional beacons from a remote location a few hours outside Toronto. Performance fell off noticeable as the frequency increased. ![]() ![]() At the time, the isolators I made used a ferrite type that favoured operation in the longwave band. At their simplest they consisted on a small 1-to-1 transformer wound with magnet wire on a ferrite toroid (doughnut shaped) core.
