Not sure what they are using for a TX now, but fair signal. - Bruce Jensen, CA, USA "CA" is a big place north to south "SF Bay Area, CA, USA" would be nicer ) . - R75& 60 foot random wire BpnJ is this "60 foot random wire" your newly built Shortwave [SWL] Antenna ? -or- an older existing Shortwave Antenna ? ? I thought it was an Inverted "L" Antenna ! -not-just-a- Straight Horizontal 'Flat' Wire Antenna ? *IF* the newly built SWL Antenna is an Inverted "L" Antenna ? How many Feet in the Up-Vertical-Leg ? -and- How many Feet in the Out-Horizontal-Arm ? =Total= Combined Feet of the Antenna Wire +Plus+ The general 'Lay' {Direction} of the Horizontal Antenna Wire from the the Up-Vertical-Leg out to the Far-End of the Out-Horizontal-Arm : N& NE& E& SE & S& SW& W& NW& N iwtk ~ RHF . . It's the new one. Well, yes, that's right, an inverted L. The vertical is about 30 feet, the horizontal about 60. Oriented nearly north-south (not checked with a compass), far end is south. Guatemala is off the forward left side if you looking the direction the antenna is aimed. How much does the 30 vertical do for you, other than collect vertically polarized QRM? The only reason, really, I built it this way was to allow the 9:1 antenna unun to be mounted near ground (the ground is not in place yet, but will be soon). Otherwise, I would have put the whole thing up high, or possibly sloped with the unun end down. Once you get your ground in place, experiment with variations of the installation. You do have a quite a bit of antenna, there. Verify that you've not got too much. Look for images, indicating overload. A pad may be required. This morning (1800z onward), the VOA relays from MDG and BOT (Africa) on 16 and 19 meters were coming in almost like locals. Bruce |
