Waller Flag RX antenna
The 160-10 meter small lot Waller Flag RX antenna, is working better than ever. Quieter with a slightly better F/B. A good preamp is a must for 160 and some gain is necessary for 80, but no preamp is necessary for 15 thru 40 meters

A Shielded Low Frequency Loop Antenna
How many turns should I use? More turns means more received signal, but more weight and difficulty of construction

With the low bands benefitting from the current sunspot minimum, receive antennas are important for between large antenna systems such as multiple Beverages,EWE,Flag
NVIS N.V.I.S antenna
There is some talk that lowering an NVIS or N.V.I.S. antenna very close to the ground enhances NVIS operation. The problem is very few people have actual measurements

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane
