Hi Steve,

I have started to work my way through your Eznec tutorials and find them really useful, Thanks. Would it be possible to add one concerning traps and inductors.

Anyone else interested ?

Any particular theme: trapped dipole; loaded dipole; loaded vertical ?

Always one for an education Steve. The first set of tutorials was enlightning.
Thank you.

Agreed, very handy. Nice way of getting people to look at things differently too. Well worth the effort

I would be interested in modeling my mulitrap dipole. It has two elements, one a 12m trap and 17m. The other with traps for for 10, 15, 20 and 40 with 80m on the end.

If modeling the two elements is too difficult then just modeling the 10-08 sect56n 5s f5ne.

OK folks - I 'll try to work up something this week. I'll probably make it a simple 2-band trap dipole - once you understand the principles it'll be easy for you to extend it to something more complicated.

I've just posted a new EZNEC tutorial on the use of Loads to create a 2-band trap dipole.

Hope it's clear and that it's useful.

Thanks Steve, you're doing it just in time for me to build a better antenna.

Thanks for the tutorials Steve. New stuff to me and it's a lot easier when someone shows you how. I'm fairly new to the hobby (Intermediate exam in 3 weeks' time though ) and since the better weather is coming I can use this to help plan an antenna or 2 to suit my garden (and neighbours).

Good luck with the exam!
