Dipole around 90 deg corner?

[SLR_65]

Hi Guys,

I'm putting a dipole up for my shack, it'll be under the eaves of the house. I plan on orientating it east/west, however north/south may be nice occasionally. I'm considering two dipoles and a switch, but then it occurred to me that maybe I could put it near the corner of the house and fold one leg around the corner.

Would that work to give a move omni directional antenna?

at that low height, it will not be directional

You can bend it any way you want. Just make sure you keep it away from metal eaves, gutter's, ect.

If the house is stucco you'll have a lot of problems with the chicken wire mesh screen. It'll detune whatever you put up within a wavelength or so.

It's not really a "V Beam", either. Those have sides 4-5 wavelengths long and a narrower vertex angle. And they're up a lot higher. Think "half-rhombic".

A 90 degree vertex angle is really too small; 120 degrees is about as narrow as I would want. Narrower = phase cancellation. YMMV.

Hello,

Besides the effect of the house a low placed dipole in a 90 degree angle placed horizontal will have a pattern that could still be considered "bi-directional".
With that said...when placed below halve a wavelength, on the sides the "directional effort" will probarbly not reach the 1 S unit difference.
And above that height it just barely will.

You would also have to bare in mind the the take off angle.
As a low placed dipole will have its main focus upwards, it will still "copy" at low angle but going from say quater wave length to a full wave length in height will provide at least one but most likely more S-units gain at long distance.

Hope it is of use kind regards,

H.

Thanks guys, I just may give it a shot to see what it does.

In my youth I ran a dipole under the eaves of a single story house and it was still directional.

My thoughts were that it would work - it's basically an inverted V placed horizontally.

I'll report back after I experiment a bit.

...In my youth I ran a dipole under the eaves of a single story house and it was still directional....

I dunno about that, perhaps the Tx/Rx off the ends was so poor that it just seemed that the antenna had gain off the broadside.

good luck
