Re: Random Wire antenna


 

I suppose there are many configurations that will work. But here is one that
I know works. I have a 15 meter dipole (approximately 23 feet overall
length) center fed with home made open wire line directly into my Z11 tuner.
No balun, I just soldered the open wire to a PL-259. It loads on all bands
from 40-10 (maybe 6, I haven't tried it). It doesn't seem to be too
efficient on 40 but it works quite well 20-10. It's only about 8 feet above
ground but I have worked all over Europe, South America and a couple of
Japanese contacts. No 599 signal reports, but solid contacts.

Subject: [FT817] Random Wire antenna


I like to create a randomwire antenna for use with my FT-817. I first
created a dipool antenna fed by a 50ohm coax. This was good enough to
make my previously announced "First Contact". I now have this rig of
my own, and also did buy an antenna tuner.

The questions is: What is the easiest and shortest Randomwire I
should create. How should it be fed and do I need to put in any
resistors or baluns.

Details: I don't have much space? I don't expect the length to exceed
15 meters. It does not have to be straight, so L-antenna is an
option. I don't mind loosing the 160 and 80 meter bands. I like to
have 6 - 40 meter band operational. I don't need outstanding
performance on transmit, but it must be able to send with it.

If you have any suggestions, and like to put graphics to explain, you
can mail me directly (pe3chi@...).

Another question: Anyone has any experience with sending on
Base/Mobile HF verticals?
