Re: Off the shelf amplified antennas for LW and AM BCB?
Thanks- I have the SONY fold up loop SW antenna for my ICF-7600G, and it works pretty well. I think it would be best in a building which blocked radio waves, because you can mount it in a window, and have the radio across the room. Loops are much less sensitive to RFI in my house. On lower frequencies I can usually null the RFI and still get a signal with my 2 and 4 foot air cores. Gary's AM and LW ferrite's for my PL-360 are much more directional. On SW I don't have too much trouble with RFI, so I have not tried to null RFI above usual Loop antenna frequencies. Many of my old tube sets barely hear any RFI at all, yet get tons of stations. The R-75 and Alinco DX-R8 are in between. Longer Co-ax would definitely help them, so that is another project. For the ULR's, the head phone volume control patch cord from Radio Shack doubles as a RF gain control on the antenna input, as some one here pointed out. The SONY antenna has switch to lower the signals too.toggle quoted messageShow quoted text
My goal is a compact portable AM and LW antenna for the beach or mountain top forays. I would not try to bring either my 2 or 4 foot air core on a vacation with my wife.
The BOG would be run across the back of my property permanently to point toward Northern Europe, but the end would be a bit of a ride on a garden tractor through the woods, far away from any power lines, and it would be miles before the beam crossed an area with electricity because I am next to a 6,000 acre forest. So maybe I'd be in a tent or little shack, where I would not want to leave electronics.
Some here may remember I experimented with a 500 foot BOG last Fall and Winter. Unfortunately it pointed toward Northern Africa and the Middle East. I was able to hear some LW broadcasts, but nothing in English, which unfortunately is the only language I speak.
Also, I was not going to phase two antennas, just trying to get one to work is enough for me now.
Thanks for all the answers and ideas. I guess I kept my original question too short. - FARMERIK
