Another advantage is that the L network always gives you only one match, at the lowest Q, minimizing the stress on the tuner. With a Pi network, there are many possible matching combinations at varyi
Mahlon, As you know, I have the 25G foldover type, and the best I can tell, is that the only time it would make a difference if you have these bolts in or not is when the tower hits the ground and br
If both dipoles will be used in the CW portion, I would tune the 40m dipole first. Considering that the 80m dipole should have greater impedance at 7 MHz than the 40m dipole at 3.5 MHz, the 40m dipol
Everybody is right. 1) The link had no place on this board, warnings or not 2) No one should blindly click on links without thinking first and making sure that's what they want to do. If such a perso
I think the Coast Guards need to buy a bunch of these little stickers you can put on the battery case of your cell phone to increase the range by 1000%, and stick them along their 500 feet tower. Tha
If you can find some paint or coating that will stick to the material, you can make them last significantly longer. It's got to be thick enough to be an effective barrier to the sun light, not only d
The problem is that the ground is not charged, the clouds are charged. Think of the earth and the cloud as both plates of a capacitor, except that the bottom plate is a few 10 of thousands of miles l
I remember seeing a report of a lightning strike hitting a tower at the mid point, between the guys. I do not recall if this was a ham tower with a large beam or just a comm or BC tower. Maybe we sho
Bill, I did not say the charge on the earth was "absolutely" uniform. It is just significantly more uniform than that of the clouds because the earth is considerably more conductive (I did not say ea
In my case, the cam is too far to bother the 802-11b network, but the hub really messes the picture. I agree with the obnoxious ads, but they have never spammed me, and they have good prices and good
Michael, I have one, similar to what you describe, near the top of my 50' tower (under the 2m beam). Make sure it is oriented such that the sun will not get into the picture. That would be assured de
I am glad that in the scientific arena theories are not validated by voting. David Robbins K1TTT e-mail: mailto:k1ttt@arrl.net web: http://www.k1ttt.net AR-Cluster node: 145.69MHz or telnet://dxc.k1t
Good point. At higher altitude, the dielectric strength of air is less, so the voltage cannot build up as much before the strike starts, so the clouds cannot build as much energy as they can in Flori
statistically the change is relatively small. In a typical area of central Florida the median stroke current is about 25kA, where in central Colorado it is about 20kA. In the highest current range (2
Polyphaser sells a rotor cable protector for 8 wire rotor cable. That may work well for the Steppir (you may need more than one). It is rated 24VAC. That raises a question: where do you buy the Polyp
Some people might object to having to take the antenna down every 5 years for routine maintenance when other antenna designs do not require it. On the other hand, the Steppir is a unique design with
This is a great idea! May I suggest an annual gathering where members would bring their most prized Rohn parts for show and tell. Awards would be given to those who have demonstrated exceptional abil
Mahlon, CC&Rs come in all shape or form. Mine, also from the 70's, are about as long as your message and essentially say that thou can't build a sewer line less than 5 feet from thy neighbor. Not ver
Let's say (as an example) that your antenna mismatch and cable lenght result in 20% of transmitted power being lost in the cable. When you run 100W, that's 20W. If you transmit 1500W, that's 300W. Pr
