Mark’s observation feeds my skepticism of a bowtie vs a flag in the specific
circumstance where a ground independent RX antenna is your only option.
A bowtie would be about half the capture area of an equivalent “box” flag and
consequently at a immediate disadvantage. If I was going to replace
Earl, K6SE (sk) advanced loop antennas on 160 meters. For
information-See Page 34, July 2000 QST magazine.
The small 160 meter bandwidth allows loop optimization k6SE gives
dimensions.

I had no idea a terminated bowtie previously existed, but does not surprise
me.
Thanks for posting.

Thanks Bruce. Sounds like practical constraints led to a
worthwhile outcome.

Europe, and USA stations, are lower in signal strength.

What specific improvements did you note when the Delta was raised Bruce?

Note: Height above ground helped a lot when my receiving Delta antenna
was re-installed higher. The bottom wire went from 3 feet up to ~6
feet at my QTH.

Mike and Don,
I have been using an expanded version of a DHDL here since November 2011. I was
forced into going this way because the neighborhood around me has become very
noisy and the antenna seems to be less susceptible to noise than my other
antennas. I call it the Dual Flag array. I
