Topband: Inverted L height vs. length.

[Mike & Coreen Smith VE9AA]

24 hours and even not one comment?

 

What if I had a  BOG for RX, buried, uninsulated radials and had worked K1N
with it during my move into a Brave New World?

Maybe I really should've said I was renting the station out for hire to
offshore stns only, to be used to work rare countries, during contests for
DXCC credits to put them at the top of the honor roll...

 

;-)

 

Sorry for asking a pretty reasonable non-emotionally charged question (how
foolish of me)

I know inverted L's have been hashed out quite a few times on this list, and
I have gleaned some knowledge.  At my previous QTH I had a 5/16th WL one
which seemed to work tons better than my current one, even though I was not
up over 40' high.

 

As it happens, on my current property I don't have any towers, nor tall
trees so I have a general question.

 

As far as a 127' inverted L goes, do I have anything to gain by sloping the
"vertical" portion of the wire slightly up to a short treetop, vs. going
nearly vertical, then the rest horizontal?

 

Example:

I have a 35-40' tree nearish to where my coax exits the ground from an
underground run.  I slope it "up" so essentially I have likely close to 50'
of "vertical" then the remainder meanders through some shorter treetops and
comes back to ground rather quickly (unfortunately it's more an inverted U
than L).  I have a few thousand feet of radials mostly in the southern
portion of the field under  the "horizontal section". A 800pf Cap is at the
base and my SWR is around 50-60Kcs at the 2.1:1 pts.  I seem to do quite
well into w1,2,3,4,8 and at times western EU/Carib.  Anything outside that
sucks.  That tells me I probably have gobs of high angle radiation.

 

Have I anything to gain by putting the coax directly under the tree, going
perfectly vertical for 37-ish feet, then, sadly, pretty much "down to the
ground" for the "horizontal" section same as the original?

 

(hope this ascii art works)

 

Ie:  This is what I am doing now (wire is around 65*-70* vertical or so_)

but I wonder of this is any better

Lastly, I could go farther away from the tree and try to get 80-90' of
sloping wire (likely closer to 45*) and then have the remainder droop itself
back to Earth.

Anyone have a skyhook for sale?

 

 

Thanks for any insight.
