Antenna model

[nfsus]

Can someone familiar with antenna software model an antenna for me? I'm curious the pattern

@Marconi or @The DB may show up here. They both are very knowledgeable at antenna modeling.

 

[The DB]

What do you want modeled?


The DB

 

[nfsus]

This antenna is what I want modeled. Horz. At whatever height is usual over average soil

 

[The DB]

The shield is attached to something that appears to be a boom, is that boom directly attached to the antenna's elements?

Also, I can't read the writing on it, so how far past the front element does that boom go?


The DB

 

[nfsus]

The boom does go past but it's not intentional. Six inches both ways. Yes the shield is attached to the boom and each end has a grounded element

 

[nfsus]

Does this help

 

[nfsus]

Crazy sometimes it attaches sometimes it dont.

The boom is not isolated from the mast. Coax comes off the boom at a right angle at the mast.

The antenna is fed from the long side

It's kinda like having 2 dipoles on each end just 180 from each other. It might not model very well. It started as a hb9cv beam and one thing lead to another so here we are. It is broadbanded and matches well. But I'm not sure what to think about its radiation pattern. Up down left right no clue. It talks but that's all I know.

Any other questions I'll be happy to answer

 

[The DB]

No further questions, and sorry for the delay, life happens and as such I haven't had the time to sit down and make a model. I will make this model for you when I get a chance.


The DB

 

[nfsus]

That's kool thanks. I appreciate it.

 

[The DB]

Actually, I do have another queation, what is this antenna made out of? Copper? Aluminum? Something else?


The DB

 

[nfsus]

Aluminum radials.

I have to learn this program myself.
