LOT of time with Tom and Natan on this and if you are interested in the results let me know and I will help out if you want. The single tower here has produced some pretty good results considering competing with other great station with multiple towers. We have managed several top tens and #5 IARU at this time, with W4PA op. There are a lot of issues to deal with so if I can help, let me know. 73, Tommy WD4K -----Original Message----- From: Scott Neader KA9FOX [mailto:ka9fox@QTH.com] Sent: Thursday, August 28, 2003 12:34 AM To: force12talk@qth.com Subject: [Force 12 Talk] Stacking C36XR + C31XR I'm building a house on a ridge-top location (5 acres). The bad news is I have CC&Rs to deal with. Fortunately, I'm approved for a single guyed 95 foot Rohn 45/55 tower (plus antennas). I'm starting to think about what antennas I would like on it. It will be a single tower station, so everything will have to be on this tower. I predominately like to do Domestic (USA) contests such as the Sprints, NAQPs, and Sweepstakes (although my baby-making activities have curtailed most contesting in recent years). I also enjoy catching the occasional new band country, busting the piles, etc., as well as 6m/2m openings. So, I'm contemplating a C36XR on top, which will give me 2 ele on 40m, plus 20-15-10. For contesting, a second tribander, perhaps a C31XR somewhere down the tower might be nice. (perhaps 40 ft spacing, obviously need some modelling assistance with that). I'd also need to sneak in 6m and 2m horizontal antennas in the mix, plus some type of wire antennas for 80/160. This is all very preliminary... but what are the group's thoughts regarding a C36XR + C31XR stack? How does one rotate the second antenna? TIC ring? Swinging Gate? The ridge-top location is known to be windy, so I may need 3 sets of guys? It may be hard to get a big antenna to fit down on the tower? Another concern, which can probably be handled with the right feedline, is that the tower has to be in the back 1/3 of the property, which puts it about 275 feet from the shack. With 100 feet up the top, that's a minimum of 375 feet of feedline! Next November, I will qualify for QCAO (Quarter Century Appliance Operator) status, so be easy on me. 73 - Scott KA9FOX --------------------------------------------------------------- Scott Neader KA9FOX (608)788-1234 / FAX (608)787-0100 Free Ham Radio Classified Ads: http://swap.QTH.com Web Hosting Services: http://www.QTH.com/prices Domain Name Registrations: http://www.YourCallSign.com KA9FOX Contesting & DXing Site: http://www.QTH.com/KA9FOX -------------------------------------------- Force12Talk mailing list provided as a service by Force 12 Antennas, Inc.
