some Nano VNA SAVER 40m antenna graphs


 

Getting Ready for the new


**** MidAtlantic 40m NBEMS net ****



testing: Saturday and Sunday 10 AM EDT on 7068 kHz (vfo)

coverage over a 300 mile radius from Philadelphia

THOR 22 check in

THOR 56 traffic (new alpha mode: w1hkj.com/alpha)


Hope to have the net begin by October 7/8 2023

Need 5-8 net control ops from the MidAtlantic region



I now have three 40m antennas to compare prop paths

1) Traditional Inv V dipole, center fed with 1:1 BALUN 66 ft

2) Full one-wave horizontal loop (140 ft)

3) 34 ft alum tubing Vertical (lashed to a tall tree) with two above gnd 30 ft radials

and matching coil at base (like an inverted T )


I had to mess a bit with the length of vertical to get it resonant where I wanted it.
