well he has, i only had time look at the 1st one (at work) but looks fantastic. many thanks dx2hunt Antenna simulation tutorial 1 - 4nec2...
Hi
The 5' firestick will work much better than a base load, but as you can shift quickly from forwards to revise on a cat you need a very good mount as the firestick is a heaver antenna than most

Hi what i was saying and not put over very well is when you modelled it and you say
>>> showing gain @ 4.31 dbi at 18* degrees which is not bad<<<
That will be a marked improvement over the original antenna that i modified.
that was a basic very cheap silver rod type that was 18 inch...

So i did make a step up from the original antenna that was 18 inch shorter and no radials then
What id like to do is get a sirio 827 try it stranded then with the long radials
and then compare it with the new vector 4000 which is the antenna i will end up with...

The antenna i want to model 1st is a 5/8 wave vertical (@27.555 mhz)
with the radiator made...
