random wire antenna WD9DMM on 20/8/14
hi, my plan is to be able to use a random wire antenna.I have 71 ft of 14 guage wire stranded insulated wire going from top of tree 35 ft up
down and in to my bsmt radio room.I am using cw qrp around 5-6 watts.
My questions have to do with using counterpoise and grounding.I have
3ground rods outside window where random wire comes in.I have a
bus bar inside next to window with braide wire going to ground rod.
Can I run some counterpoise or radials from lug on back of tuner out
and along the ground under random wire or should run wires from
ground rods. my radios and tuner are connected to bus bar.Iwould like run 2 radials for each band I plan to use thank you very much

My neighbor just told me that she can hear my cw on her tv.My antenna is a vertical 29ft.Zero 5.My radio is a Icom 718 running 90 watts .She .does not have cable.Her tv is a flat screen model
My antenna is 25 ft away from her roof mounted old fashioned
antenna.All suggestions will be welcome.Many thanks

I am limited for space.Not enough room for the 66 ft wire
suggested with 33 ft of ladder line etc.Maybe someone can tell
me another way.With only 5 watts Icant afford to loose much power.
Many thanks---Matt Furlong wd9dmm
