I just watched two PVRC's webinars last night, the August 5th presentation
and 'Design, Construction and Maintenance of Antennas and Towers for Long
Term Reliability' by W3LPL. Both were very informative! Contest Antennas was
especially enlightening in terms of radiation angles for domestic contest
and the antenna height necessary to put good signal strength around the US
and Canada. '...Long Term Reliability' is full of both tower and yagi common
sense issues and specific tips on both.
It's well worth spending the time to watch these webinars. I have DSL
internet connection and the video stream was very good.
For those not yet familiar with a webinar, it is simply a seminar via the
internet. In the comfort of your favorite chair at home (if allowed !!), you
can sit back and sip on your beer or red wine of choice, while watching the
entire seminar in 'real time'. You can either type in questions to the
moderator or if you have a microphone in your PC/Laptop, you can literally
ask questions to the moderator when time is allowed for that.

A Joint PVRC/NCCC Event - Presenter Dean Straw, N6BV, will build on the
introduction to HFTA in the PVRC Webinar on Aug 5, 2009, which was entitled
"HF Antennas DX or Domestic, What's Your Pleasure?" Attendees to the Sep 24
Webinar may wish to review the Aug 5 presentation for background information
and perspective. Go to http://www.pvrc.org <http://www.pvrc.org/> and click
on the "PVRC Webinars" button.
Arguably, the most difficult part to using HFTA is obtaining digital terrain
data for the program to manipulate. On Sep 24 Dean will ask for a volunteer
to give the exact location of his/her tower, and then show how to gather the
required terrain-profile data from three on-line sources. Once he generates
the terrain profiles, he will analyze various antenna configurations using
HFTA, discussing a number of practical "hints and kinks" determined from his
experience analyzing lots of QTHs around the world.
Pass the word!
