Maggie-

Your post re-emphasized a concern I've had with the manual use of antennas
such as the much discussed Arrow. My concern is the power lobe at 180
degrees that the antenna emits [more or less directly back at the operator].
With a handheld and a few watts power output there shouldn't be a problem to
the operator.  But you mentioned using your FT-847......

To this end, several months ago, I e-mailed Arrow asking for a polar plot of
the antenna's power emissions.  The response was "we are too busy filling
orders to run the plot".  A typical Yagi does have a significant lobe at 180
degrees..

Further, an article in the current QST talks about holding an antenna while
transmitting without any caveats.

Your comments?
