Default extra length?? 2 dipole

hi

. ... currently i have a horz center fed dipole it's
about 25ft on the hot side and about 40ft on the rf gnd side. It's a
center fed, via about 5ft of 450ladder into a sgc237 at bottom of
fiberglass mast.

the sgc does a great job of tuning all the bands my swr are almost
always great.

but i was wondering if i were to add some extra length to it , if my
performance would signifantly improve?

the only way i could do it would be to add length starting at the end
support masts, going verticlly down to the roof 'floor' and then
following the roof edge.

most i could prob add would be about 30ft on the rf hot side and maybe
20ft on the rf-gnd side



altogether it's about 20ft off the surface of my roof wich is about
175ft off the
ground ...


anyone think this would give me some significant improvements?? ie is
it worth it?


thanks

How about downloading the free demo version of EZNEC and
finding out for yourself? http://www.eznec.com

thanks for responding , i'll try to answer your question:

Mostly i was looking for a 'human' based opinion, as opposed to a
modeler real world sometimes is a bit diff

additionally i don't believe eznec will run on my mac

3rd does eznec take into account a roof mounted tuner(sgc)?, dunno
since i can't run it

but it was the practical opinion from someone knowledgeable on this that
i was looking for

i was just wondering


tnx

they have, at some interest, in antenna modeling software...

Nope, EZNEC won't run on a hamburger. :-) Dang, that makes
me hungry for a Big Mac.

EZNEC will show you what the tuner sees but more importantly,
will give you the radiation patterns for your antenna and any
change you choose to make.
