Hello LF'ers Has anyone tried making insulating bushes for the tilt over hinge and the bottom locking peg on a crank up / crank over 40 or 60 foot Versatower? How much of a detrimental effect would t
Nice idea, Chris, but any insulation would have to withstand the thousands of volts on your antenna in all conditions (wet and dry). Might work for the lower volages on higher bands but I doubt it wo
Chris, I was wondering if the possible solution might be to dismantle the existing mast and crane the ground post from the ground. Then one might enlarge the hole and line it with a very substantial
hi Chris ! when we started to do 136 in the late 90s, i had a 100 ft tower with umbrella type tophat sitting on 1.5 inch Teflon blocks. 8000 pounds of steel winched with hydraulic tools onto it. load
Chris yes this has been done I will take some pictures of the versatower that can be used as an emergency MF mast radiator for broadcast Wont be down at its location for a few weeks.. there is a lot
Hello Rik and Wolf, Thanks for the replies. Rik, the coil shown in the illustration, that would be my loading coil, right? Is the coil likely to need similar inductance to what i have now with a veri
Hello Mike, Would using the tower as the radiator itself be any more efficient than a slightly lower vertical that is supported from a guy from the top of the tower though? I am beginning to think th
Hello Pat, Digging a large concrete block out of the back lawn is not something that would definitely not get past she who must be obeyed, but a nice thought ;) Getting Putting it in there when she w
Hello Mark, I would, even just from a technically interesting angle, love to see those, please share if and when convenient, cheers. -- Best regards, Chris mailto:[email protected]
Hi all If its a fairly light weight mast High Voltage Bus Bar insulators may be worth a look. These devises have thread inserts of typically 6 / 8 /10mm and are good for 15kV [plus. I doubt you will
Hello Chris, I guess it will be more or less the same. The setup as in the right picture has the loading coil at ground level, easy to tune. Placing the coil at the top of the tower (picture at the l

Hello Rik, Thanks for the info Rik, appreciated, I am trying to keep the setup looking discrete and wonder if an up aloft loading coil might compromise that, so will have a play with the coil on the
