Hi to you all
i use a rotable V-dipole with 600 ohm ladderline for 10-80 TX/RX and and a wire dipole with spiderweb coils for 80 mtrs TX, the spiderweb coils are there to lengthen and lower the frequency that I can use.
Spiderwebcoils are made out of ty-raps and rope, every body has those materials.
Both antennas are fed with homebrew 600 ohm ladderline.
Wanted to mention just a few apects.
Tune it direct on the ladderline.
Keep ladderline away from mast and conductors at least 5 times the distance between de conductors of the ladderline.
You can even feed a beam with ladderline and use the draver as a rotatable dipole on WARC etc.
It makes a simple 15 mtr beam work as a dipole on 10-20 mtrs including WARC.
You get 4 bands for free on the 15 mtr monoband beam.
A rotatable 40 mtr dipole can be used from 10-40 mtrs as it is fed with ladderline.
Watch out different colours and wires have different velocity factors.
I use 13 gauge wire for my laddrline and the difference in Velocity Factor between diffrent insulated 13 gauge wires and a black 13 gauge (Speaker wires for car use) was 7%.
Clear PVC insulation was 0.95 V-factor.
Red PVC insulation was 0.93 V-factor.
Carbon colored black PVC insulated was 0.88 V-factor.
With a long ladderline and wire-antenna those differences can couse a lot of unbalance in your antenna system.
This fact is almost never told about and almost never mentioned on any website or antenna book.
Having any troubles with your rotator and your balanced wires, make your rotator loop out of a yard of 2 parallel ty-wrapped together center cores of RG213 or RG8.
This methode is also good to get into the house.
Having troubles making insulators for your ladderlines Order these rose-clips?
simple cheap and quick in use.http://www.handelsondernemingveenstra.nl/webwinkel/afstandhouder-p-1030.html
Or look here for detailshttp://www.amevo.nl/plantstokken_boomclips/
I have mine for about 7 yrs now outside.
These Amevo clips are cheap easy to clip on and work very fast in making your own ladderlines.
They are UV and weather proof.
Nothing can beat it in price/quality.
good luck Jos
