Hi Ken, Ron, You can feel free to make adjustments to the driven element to bring its match into range. Absent a _really_ large change to the dimensions of the DE or any change to its location on the

Roger, Thanks. Amd many attaboys for the effort and honesty in providing credible and useful information. This is how all manufacturers should behave. 73, Eric N7CL -- FAQ on WWW: http://www.contesti
To: <towertalk@contesting.com> I'm not familiar with this particular antenna. But I have experience with a number of other LPs from Hygain and others. I don't think a choke type balun is appropriate
To: <towertalk@contesting.com> Steve(s), Nobody has been advocating operating at a 20:1 SWR at the end of a lossy transmission line. The 20:1 SWR was mentioned by someone (I forget who) merely to il
To: <towertalk@contesting.com> Snip... (Others can answer most of these questions better than I can) I don't know what your soil chemistry is like. But around here it has proven extremely inadvisable
Hi all, Steve, thanks for posting this response. It permits elucidation of the final fallacy that has been hanging us up. This subject is also well covered in Maxwell's book. Take a look at figure 7.
Jim, Be sure to note _HOW_ elevated the antenna he is talking about is! At the one wavelength height, it should not matter how many radials (beyond two) there are. And indeed his results seem to show
Dave, I surmise that you bounced off our firewall. That happens if you reply to the address shown in the "From:" field in the mail header. The correct address is given in the "Reply To:" field of the
Flame sealing works well. But if you get any molten plastic on your skin, you'll regret it. Also, if your rope must be threaded through a correctly sized pulley, the blob at the end can be troublesom
Hi Scott, I think I can help with your questions. I haven't seen any other posts yet. I hope this hasn't already been beaten to death for you off the reflector. To: <towertalk@contesting.com> We rout
Phil, Yes. There are two different styles. No. The connectors are not interchangeable. The connector to cable interface for the spiral type cable is much more difficult to seal. It requires a large a
To: <towertalk@contesting.com> The impedance determining portions of the BNC connector are exactly the same as those of the N type connector. So to whatever extent the "N" connector is a controlled

To: <towertalk@contesting.com> Snip... Bill, If you are referring to the distance between elements, then the table isn't missing. It is just unnecessary. It isn't necessary to change spacing for oper
If you don't have many to do, and the tubing isn't too brittle for bending, and the length is short enough to get into a freezer, you can fill the tubing with water, freeze it, bend the tubing, and l
To: <towertalk@contesting.com> If we are talking about the cap at the very end of the element, there may be a good reason not to crimp them. The palstic cap (if it covers the end of the element) pre
To: <towertalk@contesting.com> That would mitigate the corona formation. But it would not let water escape from the end of the element. IMHO, the end of the element is the _best_ place from which to
