I just received a new batch of Phillistran from TexasTowers. This is slightly undersize at .365" instead of .375". I'm concerned this may be an issue with the Big Grips. Also instead of the outer bei
What are your recommendations on type of Anti Oxidant Cream to use for antenna assembly? Should it have suspended copper particles or not? Different antenna manufactures have different opinions. Is t
I'm just reinstalling my TH-11 and noticed something a bit strange in the specified length of the elements. On Page 3-5 there are settings for "Phone" and "DX". In all cases the DX lengths are longer
I'm putting the 40M4LLDD together and in general it seems to be well made. However a see a potential issue with the way they connect the liner loading rods to the linear loading arms and wonder if an
In my experience they do not grasp the tower legs, but are quite loose. They are held in place by the fact that they sit on top of the welded tower cross members. - Paul KW7Y ________________________
I have an M2 rotor at the top of my 130ft Tower fed with shielded cable, and a TIC ring at 92ft fed with non-shielded cable. I shunt feed the tower for 160M. All as has gone well for a couple of year
Does anybody know the formula for calculating the characteristic impedance of a transmission line consisting of 2 parallel square conductors (in air)? Thanks - Paul KW7Y _____________________________
Thanks, but I need it very accurate so need the equation for square. - Paul _______________________________________________ _______________________________________________ TowerTalk mailing list Towe
Most calculators use an approximation like W/h<<1. However my conductors are 2cm square, 3cm center to center, so stripline calculators that I've seen don't work for this situation. - Paul . ________

Does anybody have access to an antenna modeling program that uses the NEC-4 Engine (not NEC-2) and could run a yagi model for me? Thanks - Paul KW7Y _______________________________________________ __
Thanks for the offers and to the gentleman that ran the model for me. - Paul _______________________________________________ _______________________________________________ TowerTalk mailing list Tow
I'm looking for 2 N Male and 2 UHF Male connectors for FSJ4-50B. Does any body know a source for these? Thanks - Paul _______________________________________________ _________________________________
I'm redoing my Circular Polarized Satellite Antennas and rather than following the rules of running the coax out behind the reflector and down for the 146MHz antenna, I plan to run the coax out the m
