RE: NEC-LIST:monopole elevation tilt

Hi Zvi,

Here are a couple of references that relate to your problem.

IEEE Trans. Ant.& Prop.

Weiner: May, 1987 p. 488
Fitzgerrell: March, 1988 p.431

My gut feeling is that based on Weiner's Fig.2, you are going to need a very
large ground plane to get close to a peak at a few degrees.

Good luck.

Thanks everybody for your advice. The antenna I am talking about it mounted
on a continuous surface and it is conformal .It must not protrude from the
surface. However I could adjust the shape of the local ground plane in the
vicinity of the antenna .The antenna would still have the external large
ground plane. I could have a break between the ground planes in the
direction of radiation. if necessary. Would this help me ? What sort of
shaping is desirable?.
  Thanks again ,
