I need an education here... When the FCC gives the "Electrical Height" (in degrees) of a broadcast tower as 175.7 degrees, what does that mean? In this situation, I'm specifically talking about the (
Hi all, Another place this shows up occasionally is in high voltage door knob capacitors. This was pointed out by Bob Sutherland, W6PO, many years ago, and he called it silver migration. Wonder if th
Another approach to this problem is to rebalance the boom with dead weight to compensate for the missing element. If the element weighs 25 pounds and is 16ft from the boom center, then the correction
You are describing a series matching transformer matching. The formulas for this have been published in the ARRL Antenna Book for years. I have not looked at the most recent version so not sure it is
Not too long ago, when I asked why reflectors of a Yagi are longer than the driven element and directors of a Yagi are shorter than the driven element, several Towertalkians advised me to look at the
On 06/02/05 03:14 pm Phil Camera tossed the following ingredients into the ever-growing pot of cybersoup: the following. outside the window of the shack I ran regular multi conductor rotator cable (#
The likely thinking is that a full sized 40m antenna element also resonates on it's odd harmonic frequencies; third being at 15 meters. A loaded element is going to have different odd harmonic resona
If the pad is square (or round), then there could be a geometrical illusion since the center of the triangle will not correspond to the center of the square. For example, suppose the tower is 18" per
You are 100% correct, temporary brain fart!. The comment is only valid for square bases. 73/k5gw In a message dated 7/9/2005 1:48:52 P.M. Central Standard Time, n8de@thepoint.net writes: illusion <sn
Hello John, how do you test your lines and what equipment do you use? I've experimented with the MFJ 259B for stubs and phasing lines, but if it is critical, I'll order lines from M2. I'd sure like a
Beware the dead weight limitation of the Rohn Foldover towers: There are two versions; the most recent version is specified to handle a maximum of 135 pounds dead weight AT THE APEX. with a long mast
It seems that nothing is a simple as it first appears; masts included. The structural steel commonly used for industrial applications is usually made of an alloy with a 40,000 psi yield strength. Whi
Marshall, even if you were able to weather seal the rotator there is still the problem of moisture condensation inside the unit due to the heating/cooling cycle from day to night. The condensation wi

It is basically a nice eight ft whip with a heavy duty base insulator. Many AH2b owners use a CB whip with good results. 73/k5gw In a message dated 9/26/2005 11:08:27 A.M. Central Standard Time, Cqte

Bill, do you mean a metallic conductor in addition to the normal third wire (neutral) for a total of four conductors between the transformer and panel? 73/k5gw In a message dated 10/7/2005 12:57:13 P
This sounds like a version on concrete mix sold around here called "Maximizer" I notice on the bag it claims to yield a somewhat higher volume of concrete per bag of mix. This higher volume comes at
