[Antennas] How to ask a question of the list.

[ARDUJENSKI at aol.com]

I think what David N1EA and others are saying  that if you ask a question it 
should be complete. My time offering suggestions  (as some others) was wasted 
because the author appears to have been looking for  a particular response. I 
often do this with my wife. I will be thinking intently  on a subject and ask 
her a question not realizing at the time she was not privy  to the thought 
process before hand and as the Washington State motto goes: SAY  WA?

We all do this but hopefully sharing the private emails it will make  a point 
clear about being specific in your questions, but also there is a lot of  
behind the scenes chatter too. 

I know I  from time to time will be  in a hurry and so I try to correct 
myself and hopefully getting better with  time.

REMEMBER this is a hobby

Not quite enough information to offer a good  suggestion:
---is this to be left up or taken down each time?
---roof,  patio, back yard area?
---What bands?

An end fed wire using a stealth  black 26 gauge wire of about 33ft would get 
you 40m +.  See #532 at  http://thewireman.com/antennap.html

There is the Buddi-Pole that offers  portability and a variety of 
arrangements.  http://www.buddipole.com/

Indoor dipoles work generally well running  along the floor or ceiling and 
then run the ends the height of the  wall

If you can put up a portable vertical and take it down there is the  20ft or 
33ft telescoping fish pole support for a vertical

Here are a  collection of homebrew and commercial stealth  antennas

2nd floor
48'x27' flat  tar and gravel roof
two 3'x3' heat pumps next to each other
centered on  both of the 27' sides

to be permanently installed on the 2nd floor  roof

max height allowable off the roof is 36" !!!!!!!!!!!!!!!!!
I will  be allowed to rotate it

40m mainly
tunable and used on 30m will be a  plus

I already have the best ant for tx efficiency that I can get
for  the situation the landlord will allow!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
that is my  12' tall bugcatcher
end of that discussion please!

problem is:
the  bugcatcher is bad news for receive on 40m
high noise floor S-9
not the  type noise a noise blanker will touch

I need something that I can rotate  to null out these other noise(s) I hear 
in 
addition to the noise  floor

I don't think a rotatable 3' tall loop will do the trick
plus it  would be extremely hard to use as a tx ant

if its a dipole and transmits  also,
that's a plus, but
since it will shortened, and inefficient
(7'  on a leg not 33') (think hamstick)
I don't really think I care if it will  load and tx
then again? who knows?

I figure the max end to end I will  be able to do
and have it rotate
will be about 20'
probably less
10'  of stainless whip would have enough droop to be almost on the roof at 
the  ends

2 hamsticks for 40m would be 14' end to end
have a null off the  ends
and would load on 40m for tx
even if terribly  inefficient

PLEASE.......
no wires
no, try this to get around the  land lords rules, stuff
stay working within the 36" height limit
and the  limited space roof
horizontal  polarization
rotatable

comments?

One question. Are you able to run ladder line or flat 300 ohm  tv line or are 
you limited to coax?

A friend of mine had a similar  problem in a trailer park and he ended up 
running a loop antenna around there  periphery of the trailer roof up about a 
foot. If you could run the tv feed line  you might consider a loop of wire around 
the outside of the roof edge.  Alternatively you could run a 44 ft dipole 
with the legs running 90 degrees  apart.

Alternatively, especially if you have to run coax is to get a  remote tuner 
like SGC-237 or 239 and connect whatever wire you have hidden on  the roof. 
Working 40m short antennas are lossy so if possible the wire would be  best since 
you can't go high.

RECOMMENDATION: Work it out that you can  try a few antennas before deciding 
on which one. If you put up a bad design and  don't have this option the 
landlord may get tired of your requests. 

Hope  this helps
