I makes sense, crazybob. I believe that the top whip on an A99 is the main radiator so the short radials installed at that point should give the antenna a ground plane right below the whip. Trouble is that then you would just have a 1/4 wave ground plane. What about the "99's" that have the bottom ground plane kit on them? I don't know what to think about two sets of radials at different points of an antenna. The only way to know for sure is to install the thing and find out. When I take down my A99 splatter stick it will be to chop it up with an axe and put a real antenna up. Just my opinion. Interesting, though.

I thought I saw something like this before where they mounted smaller radials higher up on the vertical but for the life of me I could not remember what antenna it was until I looked through an old catalog of mine. It was called a "Jam Ram CB Power Collinear Gain".What a mouth full ! Also, the Starduster had some type smaller radials mounted up on the vertical above the normal drooping radials. These i saw in an old 1976 Henshaw's catalog. I had forgotten that the Starduster had those extra radials, but I knew I had seen a common type vertical ground plane with that setup before..(The Jam Ram)....Heck I can remember stuff like that but can't remember what I had for dinner yesterday...go figure! Merry Christmas ..... Sniper |

Merry Christmas ..... Sniper Better long term than short term memory is a sign of getting old. I have the same problem. And yes, the Jam Ram was made by Hustler and had 3 mini radials (not sure what they were supposed to do) and 3 droopy radials. Then there was the Hustler Trumpet (I had one in 1975), which had 6 mini radials in the middle of the vertical section, along with 3 rigid radials. The Jam Ram was rated at "4db gain", while the Trumpet was rated at "Better than 4db gain". How much better it really was, was miniscule I'm sure....... |

If I didn't know better (and i don't), I'd swear they look an awful lot like the radials for the 2 meter or 220 Mhz Ringo Ranger II...... |

The funny thing about those 3 little radials on the Jam Ram and the trumpet is Hustler still uses them for thier 5 and 6 BTV Hf verticles!  |
