Does anyone have a m400 star duster? I have a pdl in the air but want a ground plane to play with. These antennas adv. 7 db gain yes I know off what??? What about the LW 101 astro plane or is the maco the better ground plane?? |

The SKYLAB is the same as a starduster. REAL gain over a isotropic is about 3 db and about equal to a 1/2 wave dipole. I cut one down for 52.525 MHZ ( FM ) and it worked VERY WELL.
I also have a TOP-ONE same as astroplane again works just fine mine was disrtoyed by the hurricane in 2004 which produced 100 mph winds here.

Maco 5/8 will outperform Top One or Skylab.
Maco has a more narrow bandwidth than a Top One though. And if you live in a place that has severe winters and high winds, Top One would be the best choice of the antennas you mentioned.

Star Duster is a diskcone antenna look at it then
look up diskcones on line you'll see they do have a wide bandwidth if you need that. |

Both Starduster and Astroplane has wide bandwidth.
Height is not a factor with Astroplane, either. It can work wonders 10 ft off the ground. few people seem to believe this. It's always, "I;m going 40 ft in the air." Try that sucker at 10 ft to ring.

But, who would want to run a antenna
only 10 ft off ground? Unless that was there
only choice for installation or on a mountain.
Alittle extra height is better if possible.
I mounted a Top one in my yard at 10ft. Installed
it on the side of my house at 30ft to ring.
Major difference! I live in a hole with mountains
and other houses and buildings around me.
So, I feel it depends on your location.
