Hi folks
I experimented in many overnight car trips some inv L and short =
verticals for low bands with excellent results. In one specific trip i =
phone qso'd in 80m during an entire night trailing 20 m of awg 26 in a =
near inv l configuration receiving amazing reports. It was also clear =
the differences of high / low sigs angle betweeen inv l and short =
verticals. Presently i have in my motor home a mil std roller coil =
inside the vehicle and an adjustable whip (fishing pole, solid =
fiberglass, helical enamel wire).=20
My question is: What is better for top, with non ideal =
ground/counterpoise (i normally park the motor home in good soil, and =
deploy 4 + quarter wave roof height radials).=20
1) 30 ft vertical linear loaded whip (typically awg 18)
2) 30 ft vertical whip / silver plated - big loading coil at base
3) 30 ft whip / base and center loading
4) 30 ft vertical / 30~60 ft horiz wire / linear or base or center =
loading ( Inv L )
In summary, for transmission, their efficiencies are about the same?=20
The question is because comments about 5H3RK linear loaded whip/good =
sigs report.

Tks all, Mac
