Ham Radio QSO Parties

This installment of our 40 meter antenna simulations takes our 26 foot Inverted V, described here, levels the conductors and lowers the elevation to 10 feet above ground level.

The antenna exhibits some improvements over our baseline. Unlike the flat dipole at 26 feet this has a much higher chance of being a flat antenna since two or three 10 foot masts is a portable possibility.

The result is boring similarity with the baseline leaving only mechanical considerations in the quest for our Expedition portable 40 meter antenna.

Here is a view of the candidate antenna…

Here is the plot of the elevation pattern broadside to the antenna…

Hmmm, this is practically the same pattern for this antenna (in black) and the baseline Inverted V (in blue).

Well, about the same for high angles and ever so slightly worse at low angles.

I propose what you can take away from this might be:

• These are electrically the same
• This ten foot high antenna requires at least two masts
• The Baseline antenna requires just one mast

So you be the judge. All this really proves is anything can work if you put it up at least a little; We proved that as Ford Taurus Roadside Mobile last year.

The search for the ultimate 40 meter NVIS antenna continues, however.
