I have had several vertical antennas that were mounted either close to the house, close to a road, or close to property boundaries. (160 meter, 80 meter, and 40 meters). Most of my radials were the c
My experience was to follow the instructions.? I fooled area trying to get a nice match when the antenna (C4) was 2 feet from the gound and ended up changing it once it was up.? Worked like a charm.
I have placed multiple coaxial inverted Ls in the same tree (but fed them with separate feed lines).? My results were that there was no noticable interaction.? The antennas all worked fantastic. My p
Please be aware that the bandwidth for a coaxial inverted L is very broad. My SWR at 1.800 is 1.3 and slowly rises to 1.7 at 2.000Mhz. (The antenna is cut for 1.8400MHz and is physically located abou
My coaxial inverted Ls can be thought of as 1/2 of a bazooka. It is fed by coax. At the antenna base the shield of the feeding coax goes to the center conductor of the RG8X coax of the antenna and th
A better description can be found on pages 72 and 73 of the August 1984 CQ magazine. The only change that I have made was to use coax for the entire antenna instead of TV twin lead for the portion ab
I put on my safari hat and lots of bug repellent and took a trip out to my closest 160M and 80M inverted coaxial Ls. The base plates of these antennas are next to each other. The SWR on the 160M feed
I had 9 foot Glen Martin roof tower on my single story house in Iowa for 10years. I used a 10 foot heavy duty mast (with thrust bearing at top). I had a Force 12 C4 about 6 feet above the top of the
I use a copper or aluminum plate with stainless steel 2-3 inch #8 or 10 hardware. I then use some of the larger solder/crimp lugs. I try to insert as many radial wires in each lug as possible. Seems
I am just about to start installing my 9 foot roof tower with an 1/4 inch wall alumunin mast (9 foot) with a 3 element SteppIR mounted about 4 1/2 to 5 feet above the tower. Is the center bolt on the
I have a Linksys Wireless-G Broadband Router (WRT54GS) in my shack and have no problems with any of the amateur bands... But it does interfere with the X10 wireless cams. (2.4 gig) But, once I instal
A couple of caveats: These flexible ladders are HEAVY. I have a lot of trouble carrying and using the ladder. Make sure you use a brand that has wider steps. My first one had small round steps which
I use a fishing arrow. 1. Has a nice pre-drilled hole for connecting the fishing line. 2. I buy the heaviest fishing arrow (without any tips) and then use a screw on BNC connector as my weighted tip.
I have had very good luck with obtaining stainless hardware from FASTENAL which seems to have stores in many places. Check www.fastenal.com or your local phone book which has pointers to their stores
Although I have no documentation (or any other proof), I would not be surprised if many of the first 'towers' were windmill towers. Pretty strong and must not have been too expensive as many farms we
The type of coax depends a little on the distance from the shack to the top of the tower. Purists would probably say 9913 or 9914 or the equivalent. I have had excellent results using RG8X for distan
I second very strongly the use of the foam sprays. Not only does it kill on contact, but the stupid critters will dive into the foam to get back into the nest, killing additonal ones. 73 and be caref
I purchased mine from penninger.com. 9 foot 2 inch diameter T6061. Shipped UPS. Contacted Charles Penninger via his cellphone. 73 -- Bruce _______________________________________________ ____________
My recommendation is that you report (get it well documented with the police as vandalism). This may help get quicker assistance in the future and help with any claims with any insurance. A little ex
Hmmm, I think that an additional rope would work ok AS LONG AS the rope remained dry. Most antennas prefer to be away from conductive surfaces. Water and ice/snow tend to have some conductive propert
