Easel Di-Pole Antenna

Easels on the Roof

EVENT:
    ARRL 10-Meter Contest, Saturday, December 14, 2002.

MY LOCATION:
    Springfield, Missouri, elevation above sea level 1382 feet.
    This is reasonably good height for my immediate surroundings. To the North-East of my location, maybe 10 miles or so distant, the elevation reaches 1500 feet, but I'm not down in any valleys either. Within line of sight I am close to the top of the hills around me. I may even be the on the tallest hill. I know as one drives to and fro around here I am reasonable high and I'm not worried about getting flooded any time soon as I pretty much am sitting at the top of the hills around my house ;^D

ANTENNA:
    Aluminum Painting Easel Di-Pole.

ESTIMATED HEIGHT ABOVE THE EARTH:
    10 feet at the feed-point (the bottom of one leg, each easel).

RIG / TUNER:
    Icom 746, at 100 watts, MFJ-969, Drake Filter.
    I was able to fully load this di-pole to 100 watts transceiver output, thanks to the MFJ-969. (It has a roller inductor which makes it very easy to find your required tuning - I like this much better than the tapped inductor style.)

TOTAL CONTACTS / TIME:
    34 contacts, from 7:15 UTC to 11:35 UTC.
    Total operating time was 4 hours and 35 minutes.
    Average of one contact every 7 minutes.

DISCUSSION:
    Easels Seen from East This was the first "strange" antenna used in the contest. I used it all day Saturday. Of course, I didn't exactly work very hard at it! I didn't start until after 1 PM local time and still took breaks to smoke a couple pipes and eat lunch. (Kurt is sure right about taking the relaxed route while "contesting"!) In the evening I attended a Christmas dinner, after which I went to sleep, fed to the point of bursting - I actually said "No thanks" to a second piece of pecan pie, which for anyone who knows me, is reason to suspect a doppelganger!
    I spent the entire time tuning up and down the band listening for other stations calling CQ. I did not call CQ myself, except to occasionally check the reflected wave (SWR).
    If you can consider something like this to have an orientation, it would be a North-South major axis. In the photo at the top-right you are looking North. In the photo to the bottom right, where you are looking straight-on at the easels, you are looking to the east.
    I recall at one point early on thinking "I ought to rotate the di-pole" - then it dawned on me that I had no idea what type of RF envelope this was displaying. Although I would like to know! Should anyone care to model any of these antennas, I will be happy to post the resulting image on the web site. It would be interesting, but it is beyond my skills.
