    Hello guys, been awhile since I been here, lot has changed as well....
    We bought a house and lot of land with it, and looking for some ideas on a antenna system to go with.....have a lot of tall sickamore tree's on the land as well as other trees so height shouldn't be a problem getting here....



    So, what dipole would you all recommend for 80-10m bands would take 160m band as well ?....

    Later on will probably get some sorta beam as well...

    A center-fed doublet that has an overall length of 204 feet, plus or minus a bit, fed with 450 ohm ladder line all the way into the shack tuner will load up very well on 160 through 30m. It will also load on the higher band but the pattern probably becomes really weird. This is what I use for 160/80/75m for over a decade and it has served me well.

    The key seems to be to make it 3/8 wavelength on the lowest band of interest and ti will tune easier on the next couple of harmonic bands.

    Great kit has all the goodies to make one:

    I run a Phased PAIR of the 80m-10m version...62.5 ft each side of center(34ft spacing)...Works very well for me at only 45ft for 80m-17m...
    The doublet is simple to build, and tune with a good tuner(for that matter so is the Phased Pair) and has some good gain 40m and above. The Phased Pair (google W8JK wire beam) even has some Gain on 80m over a tuned single band dipole...even low to the ground and mostly OMNI on the lowest frequency it's cut for. Though it also has some slight broadside gain to front and rear.
    I think it's the best all around antenna one can have for HF. I like the 300 OHM line with this kit. Works VERY well!
    All the Best
