Tom W8JI, says it best,

"We know, for a given polarization and wave angle, the highest gain antenna will deliver the strongest signal to our target area. Transmitting antenna choice is reasonably simple, we want properly positioned gain. Take-off angle, side-lobe strength, and F/B ratio take a back seat to maximum gain at the desired wave angle and direction."

Therefore, it can be achieved by installing either a horizontal or vertical polarized antenna.

The horizontal polarity of the antenna is mostly a desired feature for the convenience of installing a large multiband antenna, on a small lot. It is not always installed for the purpose of transmitting with a horizontally polarized signal in itself per se.

The question is.. Do you desire long range DX communication? or are you looking to optimize your current communication capabilities outside your skip zone utilizing the effects of NVIS propagation?

Or perhaps you just want to put up any old antenna that will:

A) fit on your lot - and B) Tunes to all HF bands?
C) Single band DX antenna that will outperform a multiband antenna.

You see, there is always a compromise one way or the another...

A dummy load meets the criteria of both A and B......

If you don't want to buy the R7, let me know! I have been using one for 12 years and I swear by it more than at it!
