Topband: Topband vertical

[Drew Vonada-Smith]

Mike,

One thing that I used to do is put a 80M trap between the top of the vertical and the L wire to use it on two bands.  I know yours is not guyed and can’t support top weight.  Mine was the same; here is how I approached it.

If two supports are available, in my case a high tower support and a lower tree support, I run the wire sloping down rom the high support to a bit past the vertical, insulate it, and then run rope to the lower support so the wire is secure on its own.  I then attach a floating wire from the top of the vertical up to the L wire.  No torque on the vertical, in fact, it is even a bit held in place.  Of course, you need to lower the wire to fold over the vertical, but that is easily done.

Just a thought if you happen to have the needed supports.

73,

I have a full sized 80m vertical and a Top loaded Cushcraft 33ft vertical for 160.  The Cushcraft gets out but not great.

I was thinking about using an inverted L over the radial field that I use for the 160.  It is 30ish radials of various lengths or I have seen where people have loaded the 80m vertical on 160.  I think I recall people are not overly excited about bottom loading the 80.  The 80 is unguyed so the top cannot support anything.

I can get the vertical part of the L up 50-60 feet.

Any feelings one way or another?  I can make a switching system for the
80 vert if people think this is a reasonable transmitting solution.  I have a rcv array, so I am hoping to improve my xmit signal.
