Re: [IRCA] Favorite reversible beverage?



I have a 1000' spool that I'd like to try, so terminating at the east end isn't feasible. I think leaving it non-terminated is best. I wonder... I am using the ICE beverage transformer at the near end to go from long wire to 50-ohm coax feed into the house, so I'm assuming it can it be terminated there (from the wire terminal to ground)?

There is corn in the field now, taller than I am, and I don't see myself laying 1000' of wire through that many corn stalks (what a lazy DXer, eh?), so I might try running it N/S parallel to the edge for now - to the north and south along the field is all family-owned property. I'd move it to the field later in the fall after the corn is picked.

I have another almost 1000' length of wire I could use for that, perhaps even cutting that into unequal lengths and try the phasing route.

OK Tim, this is what I recalled as your DU's come of the back end. You're losing at least a couple dB compared to being fed from the east end. This loss is greater in the upper band and helps explain why your BOGs aren't
effective for X-band Aussies.

My BOG wires are 400 FT & 500 FT and spaced roughly 1-1/2 to 2 feet apart.
Google Earth tells me the bearing is about 78 / 257 degrees which is 2
degrees off from Sydney. The wires are fed from the west end and are left unterminated at the far end towards the east. The wires have been deployed
for several years now and go through dense woods.  I took a walk a few
weeks ago to check on the condition of the wires. Aside from the first 10 feet or so, I can't even find the wires anymore in the woods due to the natural ground covering. The ultimate high performance stealth antenna!
