a TX now, but fair signal.

"CA" is a big place north to south
"SF Bay Area, CA, USA" would be nicer )

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

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.
