The Wilson TT-45 (over 40') and the MAB are very different in "beef". The Wilson is about 160lbs (or less) and has a lighter tube section than the 242 Lb. MAB. The good news is that the Wilson will d
I have a Tail Twister II on top of my wall mounted Tri-EX 33' crank up tower with home-brew 8' 5th section and 2' tall base. Because the tower is mounted to the wall of the shack I hear every sound f
Greg, once you take the sections apart is becomes very obvious -- fear not, it is very easy, especially if it is a two section tube tower. You may want to add a thimble to your collection of stuff fo
MFJ makes an inexpensive kit for the 269 analyzer that turns it into a grid dip meter that you can then use to test the traps for proper frequency etc. Here is a good read about rebuilding the A3S in
A big thanks to everyone for your responses (group and via email). If I can't quiet the TX2 down I may have t replace it with a quieter rotor. Regards, John NA6L The text below about the challenges i
Wayne, the ridge should give you additional gain especially in the area that slopes away from your antenna site and that is a good thing. If I were you I'd consider using a beam with more gain than t
A little shot with even a cheap electric pressure washer will quickly remove your small areas of latex paint and leave the galvanizing intact. Regards, John. I have a HyTower whose 24' of base tower
Gary, I remember seeing that information on the Rohn website not that long ago but IIRC 3 sections (2 above the bracket) would be too much for a full load rating. OTOH, you might get away with if if
Another consideration would be to properly torque the bolts based on the materials involved. Too lose and they can work their way out and if too tight they are prone to stripping. Regards, John NA6L
No hi-tech required, during a sunny day when your tower's shadow is the shortest it will be pointing North. If you want to get fancy just input your Lat. Lon. Into this program and you will have your
Yes, post a WTB (or will remove) on CL and just keep posting it every week. Also get on the SSB and repeater nets in your area and get the word out. Post a WTB ad at your local HAM stores. Mention th
Bruce, you may want to look into a clever device called a Hazer. It is like a little cart that will attach to the Rohn 25 used to haul the antennas up and down the tower -- your antenna would mount t
Unless you are on totally flat ground for miles around you'll need to run the Microdem program to import your exact location into HFTA to actually get the correct gain and take off/landing angle info
David, I have found that HFTA (with Microdem) works as advertised. The program accurately predicted how my antenna installation would work by antenna height band, by DX destination and azimuth based
Jim, if you did build a simplifiied way to enter the exact location of the antenna to import into HFTA you would be a hero to the masses because Microdem is a true PITA! Note that unless the site is
Yes, the handheld GPS will work just fine...... AND, you can use Google earth to find the exact location of your tower for free (place the curser over your tower or proposed locations and read the La
Yep, the "inches" was a bit of a stretch but at my QTH (on edge of a steep 225' hill and with nearby 100' "lumpy" hills) by using the program to move the tower location around -- toward/away from the
Mike, do a Bing or Google search "rebuilding Cushcraft A3S" or "tuning Cushcraft A3S" and you will find the resonant trap frequencies and cap values on a site where a guy has some rebuilding info for
Roger on the power lines, AND I'd suggest doing a survey for other "domestic" noise. In my neighborhood and many others it is the "Tap Lights" that are the RFI devil incarnate! They are the little de
Marlon, here are a couple of curve balls -- #1 Unless the event is a felons convention, don't do real time processing, batch the transactions and process them later. I have operated businesses that r
