[IRCA] New Flag Antenna results



Jim Renfrew, Holley NY

Some of you who attended the NRC convention heard Neil Kazaross' workshop on flag antennas. With his guidance I've built one. Using three trees in a line, aimed NE/SW I put up the Flag in the front yard, with the lower wire 8 feet off the ground, and the upper wire 25 feet. I couldn't get any higher with the 40 foot ladder, two trees were too narrow to support the ladder at that height, and the third tree was a mess of branches. If necessary I can drop the lower wire to ground level after the lawn-mowing seaason, or even put it under ground with a conduit. The length of the antenna is about 85 feet. Neil provided a 9:1 transformer. There is a 475 ohm resister at the far bottom corner. There is a 125 foot coax into the house, but there doesn't seem to be appreciable signal loss. I use a Drake R8B. Other wires are a south wire (200 feet), an east/west wire (700 feet), and a northeast wire (about 600-700 feet). Flag results are very positive. Most of these receptions are not found with the northeast longwire (or substantially weaker), but present with the Flag. Stations to the southwest, like WLW, WSB, WHAS, or WTAM, are depressed about 15-30 dB using the Flag.

Here's what I've noted tonight, times EDT:

2229 774 Koranic reading, faded before I could get a Global Tuners receiver to try to match it. Egypt likely.
2243    1089    UK excellent
2244    1341    Weak audio, North Ireland likely
2250    1377    France, very good
2251    1521    Audio in heavy WWKB slop, Saudi I suppose
2252 549 Arabic, something here but language may be wishful thinking. Algeria and Germany have been heard here.
2253    693    BBC very good
2254    738    Spain, fair, enough to ID language
2255    747    Netherlands    "I Can hear Music", appropriately
2256    855    Spain // 738
2246    1053    UK I guess, but too weak to ID or to compare with 1089.
2308 1060 CKMX Calgary - matches web audio and song list. Blasting KYW on all antennas. Fades in and out.
2316    1134    Croatia now off at this late hour, but a het is noted.
2318    1215    Absolute Radio

Yesterday at 1915 I had an interesting signal on 783 kHz, might have been Mauritania or Syria. I couldn't make it match the Mauritania shortwave station, and I couldn't find a web audio for Syria that worked. It was not Barcelona, Portrugal or Germany. I think this was Syria, heard last year in December.

I'm disappointed to note that more than a few Global Tuners receivers are no longer listed.

Thanks to Neil and Chris Black for the guidance on putting this together.

Bruce, I'm sorry that this isn't in the form needed for IDXD, but perhaps you can make this into a feature after the regular reports. People who attended the convention will be interested in this. More than a few people have expressed an interest or intion to build one fo these.
