A brief note on my experiences on 75-80 m: I have K9AY receive loops, a
F12 Sigma 80 OCF vertical dipole, and an inverted V with the apex at
about 40 ft and the ends about 10-12 ft above the ground. In my
experience, any of these antennas can be best for receive -- it depends
on the day. Often, the K9AY loops are quieter, but not always and the
difference can be striking between antennas. For transmit, the inverted
V wins hands down for anything inside of about 600 mi or so. Within that
same range of about 600 mi, the Sigma 80 is always much worse as a
transmit antenna. However, on DX, the Sigma 80 is far and away the
better transmit antenna.
For receive usually, but far from always, the K9AY loops are best. But I
always check all the antennas for rx effectiveness and choose the best one.

My RX antenna is my TX vertical too. Conventional wisdom says you
"have" to have a receiving antenna and a vertical TX antenna to work
DX. I worked my first 80 countries or so with an inverted-vee, 45-feet
high at the apex and ends about 6' high. Then I installed a 55'
inverted-L and worked another 60 or so. Am I a top gun? No, but my
goal of 9-band DXCC from one location is achieved.

No, my best 160m receiving antenna is my vertical.
Very weak signals are not audible on my receiving antenna.
My receiving beverage antennas 120-160m long are only good for
directivity
like suppressing qrm.
