i auctually thought about doing this exact same thing. if this is yours
please keep me updated
That doesn't look like an Imax to me. It looks more like a Hygain type mult-element vertical. Maybe you are just referring to the Maco GPK.
No I have not tried one. What size mast does it fit and does it come with radials? If so, how long are they?
and this thread ........
this is more like a reference i have a imax 20 feet off my chimney with two sections of 10 ft mast and no ground.in the back yard i have a spare maco 5/8 with a hub and 4-10ft ground planes.i was thinking of setting the hub at the bottom by the feedline and i was not sure about whether i should isolate the antenna from the mast or not. thanks for those links booty i already read through all of those and nothing seems quite clear.i found a couple of posts on the net about people who have done this,one guy claimed he modified the bracket on the bottom and put 4 ground planes just under the tuning rings.the other guy with that picture claimed the same only he mounted them at the bottom by the feed like the picture.
I would just mount it on the masting directly below the antenna feedpoint. Otherwise, the IMAX will just use the masting for the ground plane. That is the way I have mine set up - BTW - works fine and has a low SWR to boot...
thats not mine hotrod but this one is!this is the end result.top section 102 stainless making the radiator 23 feet and the overall antenna 24 1/2 feet.the maco ground planes are stretched out to 104 inches each,that was stretching.as for the match it was not affected at all.i dont have an antenna analyzer or tuner so i am going to have to go by ears and reports.ears may have gotten a little better or might have just reduced noise a little not to sure yet.i did get one report so far at 55 miles that said he usually has no s units on me but had 1-2 on me last night.
hows those mounted?did ya mount it on antenna just below
the tuning rings.or on the mast itself?
on the mast as close to the bracket as i could get about 1/8 inch.
