hi

wanted to help a fellow ham set up an antenna on his terrace
it's kinda a best effort attempt naturally the building won't allow
anything 'outside' so he just has the confines of the terrace


the total length of the longest side of theterrace

about 15ft on the longest side so here is my question


i was going to use a sgc 237 as the dipole 'center' and extend the legs
from there

since the total space is short would it be more advantages to make the
leggs a coil like a slinky? will this be of any real benifit?

if so how many ''turns'' and how big dia each ''coil''


my other option was to mount the sgc on the center of the celing extend
the dipole horizontally about 7ft each side then down to the floor
vertically like upside down U



i wondered how a loaded verticle would be or even using a verticle whip
into the sgc because i am not shure how i could make a 'radial'
/counterpoise

i'd like to give him at least 40m to 10 i realize that the sgc
really can 'tune ' anything but if it's too far outa wack (away from
resonance etc) it would just work poorly



he put up a glass metal framed enclousure around the terrace the metal
is isolated but a strange shape for an antenna i could try to load
that perhaps using a wire around his apt as the counterpoise? would
this be effective?


he's up about 20 stories on a high point everything elese is lower far
as eye can see to the horizon


any help is surly appreciated he's an old timer that wants to get back
on the air
