home made quad band vertical band in the air

[mr_fx]

ok its in the air ( http://www.worldwidedx.com/amateur-radio-antennas/155941-a99-becomes-quad-bander.html
)
20m is a little long, resonant at 13.2Mhz...

15m is also long, I think around 20.5Mhz

10m is long at around 27Mhz

6m is fine at around 50Mhz, might shorten it a little more

for radials I did 1/4 wave + 5% (or thereabouts), 2 on 20m, 2 on 15m, 2 on 10m and 4 on 6m, I think that the 20m radials should work on 6m as well as they are around 3/4 wave @ 6m, they were made out of old RG6 quad shielded coax I got an end of a roll from my friend

its feed point is at around 25-30 feet

Used the tuner and on 20m (it's around 3.5:1) and worked Nova Scotia today.

Also I can hear a baby monitor at or around 48.85Mhz

I tried to work a local repeater on 6m, best I could get was an s7 on the meter with a bit of pop corn... sad thing is I can do that on my mobile, and its 25 feet lower on the ground


this pick is taken from on top on my roof

SO while I was looking at this post and I saw my antenna... I was think, "I wonder if this is what I am getting a divorce, lol

well it tuned up great, nice lower reactance and a good match on all bands (20/15/10/6), well at least in the sections of the bands I intend to use.
