Post dipole 40 poss 80
steve and chap's im thinking about doing away with my hustler 5btv atm ground mounted on a s/steel pipe 5 foot ish only 2 counterpoise wires for 40 out as thats all i can get out..!

im contemplating a 40mtr dipole poss including 80mtrs what is the best way to sort this out...

i.e. whats the longest dipole i would need or shortest to get a good result

i do have some space not alot but some which means asking the young lass next door to borrow a tree in her garden.. this is 80% possible if not i have very little room

any help plz chaps

cheers regards sean

Sean,

Some options are:

1) 80m/40m fan dipole. Length needed about 128ft
2) 80m/40m trap dipole. Length needed about 108ft
3) Doublet fed with ladderline from good tuner. Length needed about 100ft.

I don't know what height you can manage, but for DX on 80m/40m you might be better off with something like an inverted-L

73,
Steve G3TXQ

Hi Sean
If you had the center just below your cobweb what length's could you fit either side
as an inverted 'v' ??

hello ian an V is not possible mate here not without it looking totally pathetic... prob the most i can get out from the top of the cobwebb mast to this tree is approx ( without getting it measured up ) 70ft at the max..

what i could do with is another rotary dipole like the comet or cushcraft d4 that i let simon have...!

and sell the hustler 5btv as all that is used for is 40mtrs.... wasted really

If you've got 70ft and a tree Sean you'd get a trapped inverted L in no probs which could cover top band too. A Western HF 10 or 1/2 G5 with added inductors would cover 80m too but it would be a compromise and a fair bit down on performance compared to a half wave dipole.

With a 70 foot run, if you had the height to drop about 20 foot of wire down off each end, the doublet or trap dipole option might fit.

ZS6BKW could also be an option.

There are many dipole options for 40m and up in a 70ft run; but he said he also wanted 80m if possible.

Post Re: dipole 40 poss 80
Not a must tho steve... I need to measure how much room I actually have might be a good ides I suppose. ...

I would be happy with just 40 mtrs probably. ..

Cheers guys any further info..

Post Re: dipole 40 poss 80
most room i have is 63ft maximum a L is out the question needs to be a dipole for sure.... or a end fed

not bothered about the bands above 7mhz

or if the wire going into the tree branches would not hinder the antenna to much i could scrape about 70ft max

antenna height would prob have to slope towards house from tree to gutter height about 18ft

Post Re: dipole 40 poss 80
a 63ft horizontal run is plenty for an inverted L or am I missing something? If you can go 25ft 'ish vertical at the tree end you can get a 160m up trapped L in that space. You can always dog leg it at the end too if you're pushed for space.

Ok sean didn't realise. So it's looking like a dipole mate unless you can put some serious creeping in with the neighbour :D
