What's Missing ? - Point 'B' for the Shortwave Radio Listener
(SWL) who does not have/make a Point 'B' in their backyard
-but- Does have both Points 'A' and 'C' the Sloper Antenna is a
very good 'choice' in Shortwave Radio Listener (SWL) Antennas.

While -IF- a Shortwave Radio Listener (SWL) has/can make all
three Points 'A', 'B' and 'C' in their backyard -then- An Inverted
"L" Antenna is a very good 'choice' in Shortwave Radio Listener
(SWL) Antennas.

Again - When the Shortwave Listener uses a Ground Rod at
Point 'A' with a 9:1 Matching Transformer and Coax Cable
feed-in-line with one or both of these SWL Antenna 'choices'.

You still have to keep the unshielded part away from dirty mains
electricity or you will pick up noise.
