Re: Topband: Wanted - Hardline connectors
At my (former) CA ranch QTH, in the hills only 4 miles east of downtown San Jose, our cats weigh 130#. Sorry I can't send the game camera pix of the gorgeous mt. lion taken a couple of weeks ago near my spring. He/she looks happy on the diet of cats, dogs, coyotes, lambs and rarely a jogger. They have left the cattle alone.

Re: Topband: Spitfire question
GE Eddie, Felipe, some direct mailers and all, seems, the spitfire array got some interests, I got also some direct mailed questions. I will try to answer, and try to remember my tuning way 2003 - 2006. Just found some, maybe 20, Din A4 handscribed papers, from tuning procedure 2006; but need to remember some details not wrote down :-) Also I need to update my homepage; newest HAM-radio details are 6 years old, there changed a lot. At first, description of my array and anything around: - center tower is 27m high, grounded. Fired by gamma-match for 80 and 160m. Caps are now Variabel VACs for GU84 power (homepage not updated) - Radials: Using ~120 radials, between 10m and 30m long. Additional buried 4 x (10mx0.6m) chickenwire. During Winter 4 to 6 times chickenwire 10m to 25m long. Around centre tower 16m² chicken wire - Unused elements of the array are grounded via 3mm Cu and the radial net. - Array Wires had been ( shortly destroyed by a storm :-( ) 1mm copper with steel inside. - QTH is relativly flat and empty, only to SW over W to NW there are less buildings. Trees and bushes are not very high or far away the other directions. http://www.df9ox.com/e_afu_rxants_bev.html - ground seems to be very conductive, QTH here near a main german river, Elbe (4km). Groundwater in summer 1,4m, winter 0,7m deep. For my beverages transfering -12V via ground is no problem. My array seems to be working ok (80m) I can see up to 25dB f/b, up to 35db f/s. Gain is up to 6dB. But often it is also much lower, depending on elevation angles and conditions. All compared to the single center tower. When using the single center, everything else is grounded. Reference *1: I will use some abbreviations (W1,W2,W3) down, this is the file: http://www.df9ox.com/docs/Spitfire%20Dimensions%20(other%20bands).JPG Reference *2 for the array description is: http://www.df9ox.com/docs/FVR%20Spitfire.ppt @PY1NB No, I do not have any files for NEC. Maybe John W1FV or Fred K1VR as the authors can help out. All I find around 2007 in internet I mirrored on my homepage. ON4UN described the spitfire in chapter 3.7.4, I think he modelled it with NEC. @LU2DKT Hello Eddie I did it the same way, tuned it for maximum f/b, but used no caps at the corners, changed the length. Especially changed W3 (reflector only), w1 and w2 (director and reflector). I followed *2, page 8 and 9. Thatswhy I gone only for f/b, because gain should be ok in that small QRG area, while gain area is much broader. Starting point was good f/b on 3650kHz with the aim of 3510kHz. So I need to make something longer. 1 - Did you just adjust both elements in one direction for max f/b ? or gain ? 1. Started with the reflector part, W3, later I made some tests with the director part W1-W2. Always changed all 4 directions in the same way, but tried to find some differences between the 4 directions in the evening. But this did not happen here, changes were equal. Was looking for good f/b. 2 - Did you start with the dimensions given by the authors and then change it a little bit at a time ? both of them or just one of them and then the other? in which direction adding or shortening 2. Yes, started with the given dimensions. Changed it typically in 0.1m steps; if I saw a result like 0.1m makes 15kHz, changes like 0.2m or more were done. At first only reflector part, W1, later I made some tests with the director part W1-W2. If I saw I was above 3510kHz with best f/b, increasing; otherwise decreasing. 3 - Do you have notes about how much your element length differ from the original design? could you share those numbers? 3. Yes, I ended with W1-W2, director, 0.3m longer (W1 26.9m = 27.2m), reflector part W3 1.1m longer (W3 3.5m =4.6m). 4 - Did you measure element resonance after you antenna was working? how did you measure? (in order to repeat it in here) 4. Yes, I did a lot measurement with my MFJ 259 at the corners (W1 W2), also after finished tuning. But I am not sure with my handscribed papers at this point with exact F-resonance versus dimension of W1, W2 and W3. 5 - Finally, how do you achieve omnidirectional radiation? did you just open at the corners or ground each element? 5. Grounding all elements 6 - If you ground it, how do you do that? a ground pipe o connect it to the vertical radial system? 6. Unused elements are grounded via 3mm Cu down the post and connected to the radial net. Eddie, don´t know whether that will help you. For my understand of the array you still found that best gain point if you are in the maximum peak of f/b. You measured 1dB gain at 0° elevation angle, thats ok, maximum gain is 20° elevation. You did yet not seen any noticeable effects on signals from EU and PY. Maybe because of still no flat angle conditions? I see many times also less gain, but f/b is good. Other days there is really good gain, and less f/b. And another day there is less f/b and no gain.
Topband: Need Help with First 80M 4-Square Tower Location
Hello, Now that my 100 foot tower is installed, I would like to assemble a ground mounted 80M vertical 4-square array. Each of the 4 vertical elements would be the full ¼ wavelength long and I would use 60 radials of ¼ wavelength (in the air) length at the base of each vertical. Where the radials overlap, I plan to solder the radials to a 2” wide copper strap. My question is, what is the minimum distance from my tower can the closest 80M element be so the tower does not impact the gain, F/B, and directivity of the 4 square? Is there a rule of thumb for this situation? Just as members of this reflector helped me through the building my first tower, I would really appreciate all the help you can give me on this newproject. 73, Wayne KK6BT _ Topband Reflector

ON4UN built such a wire 80m vertical 4-square around his full-size 160m vertical. The 80m array was 20 meters on a side and used a single elevated radial elevated under each element.

Re: Topband: Coax rodent protection
My squirrels were gnawing the top rail of my redwood deck and where they urinated it bleached the wood.

Those (#($((%) squirrels --eastern Grays, which are an invasive species here in CA--are very aggressive and push out the native squirrels, After 20 years of no problems, they chewed up my rotator loops on my treetop array, which eventually caused me to replace everything, at enormous cost.

Re: Topband: Coax rodent protection
Wonder what type of urine you use out here where there are no predators like that the deer have ever seen. The deer come through here by the hundreds at a time, Axis deer that have been introduced here many years back, they provide table fare, but sure are a nuisance, beverages have to be 10ft plus high, anything green in your yard is gone the next day, not much they wont eat.
