im looking for an easy to assemble - user freindly base antenna
cost isnt an option
preferably a ground plain design with at least 8-15 db gain all ideas considered
 

to get real gain of 8-14 db I think you would need a 4 element beam? If my understanding is right 1/4 waves are all about the same and same for 1/2 and 5/8 wave vertcals they are all about the same in gain.
look or google Dx Antenna Systems tons of info.....too much at times....but worth a read or two.
 
I-Max 2000 easy

I-Max 2000 ,Just screw it together run your coax and start talking,You want even have to wary about SWR (Very user friendly)
 
Banned already? And I was wondering what he wanted 8 to 15 db gain over?

Dipole? Isotropic Antenna? Some random length of wire?

Oh well, guess its to late to ask now...

There is no way a ground plane antenna will give you 8-15dB.

If you want that kind of gain (I assume dBi) then you need to look at beams. A simple one to build is a Moxon rectangle. One for 11m will end up around 11ft x 5ft. There are plenty of Moxon antenna calculators on the internet. You should be able to build one quite cheaply and in a couple of hours. A TV rotator would be more than up to the job.
 
Uh, where did he go to??????? What did we do scare him away???????
Gezz tell someone the truth and they run.

Yeah right, a 4 element beam has about 9 BD gain in the real world...:laugh:
