I am helping to install a 135 foot dipole on a hillside for HF
activity. The antenna will be at least 45 feet from the ground in any
direction. I can believe EZNEC so far as the effects of ground on
impedance. but I am at a loss when it comes to considering the
patterns on the various bands. The ridge is about 200 feet from the
antenna.

This is for a club member who recently upgraded to General Class.

Since the ridge is close to the same height and south of the antenna,
I am guessing that the computed charts will be a good representation
of the northern half of the antenna. NVIS should not change much. The
terrain may work as a reflector for over the pole operation. I am
afraid the antenna will be of little use to the south.

I expect we will eventually need to do the best we can with an antenna
on the top of the ridge. When the snow melts I will try to climb the
ridge for a look-see. It will likely be difficult to install due the
dense trees.

Any comments, advice, suggestions etc. are appreciated!

just put it up, hook up a tuner if the radio doesn't have one, and
have fun. you can spend all your time modeling trying to figure out
what it may look like, but if you are limited on how you can install
it you can't really control much anyway. an antenna laying on the
ground works much better than one that is only in your computer!

No argument from me! It is going up as planned as soon as the new
General gets a little more time to work with me on the project.

The hillside we are working on is a little tricky for us to deal with
while snow covered but in this part of North Carolina it does not snow
often or stay long.

We need to keep his enthusiasm up with some positive results.

I agree, just put it up, feed it with open wire feeders, tune it and talk. What you get is what you get.

Занялся своим автомобилем, подремантировать, наладить. Где можно найти качественные запчасти ЯМЗ подскажите?

I really do not know how to answer this reply...

John, I hope you didn't click on the link, it's probably a virus.

I put a lot of trust in my Norton Internet Security. The link is in
Russian and appears to be about an engine.

I don't trust anything by Norton.

It is all relative!

I have had my problems along the way but it is the best for me that I
have found.

If I compile a program without flipping the appropriate switch in
Internet Security it promptly deletes the exe because it does not know
it!

It was a pain at first, but now I like it. The big problem is the
cavelier manner in which Microsoft software is generated.
