That wont work on the LM470 which the original poster has because the tops of the section tubes are "swaged" together and form the sliding part of the tower. k7puc -- Original Message -- From: "Rick
I would like to listen for the HAARP signal but I can't figure out how to set my ORION 1 to the general coverage mode! If the info is in the manual it must be very obscure? k7puc ____________________
Check out the basic strength of the steel used for the two towers. Several years ago, before Tashjian took over the sale of the Triex line, the steel used was changed and claimed to be considerably s
Has anyone tried modifying a Steppir Monstr with putting a loading coil in each side of the feedpoint (with relay to switch the loading coil in or out)? According to my calculations, some 20' of the
Out of curiosity I added 9 directors to a 4 el yagi model in EZNEC. Same spacing and length as the two already existing directors. The gain increased with each added until the 9th element was added a
Is the gain reported in antenna models a gain of: E (electric field), I (magnetic field), or W(watts-W=EI)? Also, Is the S meter in receivers in E (S9=50 microvolts) still in E when the scale switche
Why does a dipole in space have a radiation pattern shaped like a doughnut i.e. no or less radiation off the ends of the dipole? Related to this question: Why is the radiation from a dipole over grou
I replaced the k1550 winch with a k2550 winch but it was still pretty difficult to crank so I modified the raising (layover) pulley arrangement by adding two more pulleys to get the mechanical advant
I would like to model the 80m wire option of Steppirs dream beam. Does anyone have the dimensions and configuration? Or is the model results available somewhere? k7puc _______________________________
Some backhoes( larger ones only I think) have a hydraulic telescoping arm on the outer limb. This allows the backhoe boom end to be positioned at the center of the hole to be dug and the outer arm ca
Please explain the difference between "lateral force" and "the moment inherent in this type of structure" and how they effect on tahe strength of the foundation. k7puc _______________________________
I did not use the ears on my two LM470 towers. Instead I added two pulleys, one at the tower and the other at the top of the tilt fixture. This gave a pulley advantage of three rather than one and ma
My how times have changed. A wire antenna farm in a deed restricted half acre of land would have been classified as a mediocre contest station at best--even with 90' tree supports. What class are the
My two LM470 towers were purchased several years ago (Just after Triex decided to stop making them) so the design might have been changed? I also had a HDX572 tower for comparison--both with their ra
Thanks for reminding us where to find this information. It is on page 7-29. While watching my Steppir Monstr whip around even in moderate winds I suspect that it isn't the wind velocity but rather th
If I am reading this response correctly, then any metal anywhere decreases the radiated field from the driven element?! I am not discussing directivity loss or gain--I am just curious of whether the
Readers interested in the merits of Steppir antennas may be interested in the following observations and predictions: 1. Yagi type antennas (fixed element length) have been used for many years with v
I have a 3 page sales brochure on the LM470E put out from First Call Communications, Inc. who was the sales agency for Paragon Mg. I believe Paragon had just taken over the manufacturing. This brochu
