Hi Guys, I have just updated my antenna comparison chart with some
enlightening plots that show antenna comparison in 3D.
Interestingly enough my experience is as you get to the higher RDF antennas
each dB seems to be very important.
Frank is quite right , One can never have enough receiving antennas.

Hi Mike,
Beverages, four squares and 8-circle arrays are all excellent receiving
antennas. Based on much on the air experience, my W8JI passive 8-circle BSEF
arrays have much narrower beam width than my
580 foot Beverages and especially compared to the broad beam width my full
size transmitting 4-square. M y 8-circle arrays also have very low side lobe
levels. The 8-circle has a high RDF value because of its narrow beam width
and low side lobe levels.
Every year we make many QSOs using the 8-circle array that could not have
been made with any of my other receiving antennas; however probably 99% of
my QSOs could have been easily made with either a Beverage or the 4-square.
It just depends on how important that one percent is to you.
You can never have too many antennas...

According to what I read there, there is little difference between the two.
That seems odd. Was some information left out, or did I read the wrong .pptx
file?
