I think its called a modelling program? I was told a long time ago that's
there is a program where you can input the shape and size of an antenna and
it will predict how well it would work.

Is there such a program and how simple is it to use?

At the moment I'm trying all different setups to try and get the best I can,
because of the space and the neighbours.

Many thanks

If I join some extra wire to the ends of the G5RV half size and bring them
down towards the bottom of the 300 Ohm slotted feeder to make a triangle
shape, kept vertical. Would this radiate ok or would it be a waist of
time?

Is there a modelling program I could buy for HF antennas?

Thanks
