Default Home made antenna question??

I was thinking of 4 radials about 8ft length.

Now I think because of height and present elevation and the big tuner it
will function safely, what would be the reasons why not to use this? I am
sure there are loses at the tuner, loses at the coax, loses becuase of poor
gnd planes lengths and numbers, but there has to be some gains. It works
would be a big gain.

Would there be mass interferrence on anything?

Now here is my querry ,,, I have a omni antenna I purchased at ham fest
years ago. I had it up on the tower for SWL for longest time and worked
well and also worked well when in transmit.

i used the big tunner to keep what I thought was safe levels of returned
power. I want to put this back up and use with big tuner and 1970
transceiver.

Now I can fabricate some aluminum gnd planes to go with this, this should
be on the ground but I want it in the air. While the traps and entire
antenna looks good shape, how can I tell if those traps are in working
shape before spending all the time cleaning it up, erecting it, etc etc,
only to find it is dead? The traps are completely sealed in there, the
antenna looks about as old as the transceiver, if not older. I am on a
shoe string budget of course so I cannot buy one of those fancy all band
omni antennas, I have to build.

Please comment on this antenna and my ideas about getting it working 50
feet above the gnd.


To check the vertical without any special equipment, you may have to
install it at ground level and see how the SWR is.

I do not think I would try to put it on the tower. If you look at the
instructions, you will need atleast 3 or more radials for each band and
some of them will be about 60 to 130 feet long.
