Fan Dipole Spacing

Roger that.Thanks CK

WAIT!!! I SAID THAT WRONG!! I changed it above. The reason is that each element affects the tuning of the others. You should tune the lower bands FIRST and work your way up in frequency. Sorry about that. I still am having brain farts after the multiple pulmonary embolisms left me short of oxygen a month or so ago. Still thinking about the days we said to go UP the band but dropped in frequency since we were talking about wavelength not frequency. I guess it's an old hold-over from the 80/160m days.

Leave it all connected. Tune 6m to where best...then adjust 10m if it moved "dramatically." Otherwise go with it!!!

Holy Moly, I hope you are doing okay after going through all that.

I hadn't started yet so no loss. Thank you much for the info.

Hey...don't worry about CK...He's to Anori to go anywhere! Ask his better half the Nurse!!!!

Put all wire elements in place and start tuning the higher bands first and work your way down in frequency ie. tune 10m first then 6m etc.

Wouldn't higher first mean 6>10>12>15>20, etc..?

Hope you're right Gary, we need CK around here. He's a voice of sanity.

That would be the edit that I missed. Corrected above now. LOL Thanks!

Well that is something I rarely get accused of.

Yeah it was six weeks ago today. Dr. said I had four.....one in the left lung and three in the right one. Spent almost 24 hours in the ER as I was too unstable to move upstairs to a regular room. Ended up spending a whole week in the hospital, then strict rest at home until now. Wasn't looking too good for a bit but MUCH better now. I am going back to work tomorrow and see how things work out.

Well, you and AS are the voices of sanity here in my book and I for one am glad you do what you do.

but MUCH better now.

Very glad to hear that and we'll throw a prayer out there that's the end of that particular issue for you. Good luck at your return to work.

Very 73

If anyone's interested the Cobb-a-Fan 2000 has been taken down and will be replaced with proper wire elements in an Inverted V rather than lopped-off whips in a flat-top. I didn't care for how it was affecting my 10m Inverted V. The new 6m wires will be parallel to the 10m elements (separated by 6") rather than at a 45* angle. Hopefully this will work a bit better. I may call it the Cobb-a-Fan 2000 2.0

Inverted V tends to be more VERTICAL...most certainly close to ground less than 1/2 wavelength ABG....just a thought...I liked the first set-up.... but OK...too bad you missed a good 6m morning.

MN/TN/TX/MA/CT/VA//FLA x 3/NC/OH/MI/AL/KY/LA... All worked in about 90 minutes time!!!!GREAT Tropo...bet the 2m guys having fun also.

Two meters was very interesting Sunday morning, I worked several stations on two meter SSB yesterday into Pacific northwest.
