N4GI was asked: In SO2Ring a 5-band LBQ, a C-3E/A & now a wire yagi (homebrew DF4SA) - I only use BPFs. Other than close to harmonics, I can still hear pretty well. 2m above the wire yagi is a SteppI
K4MQG further reported: If this is an older SteppIR & therefore came with the original tubes, something to remember... Apparently the dielectric constant of later tubes is different than previous one
K3MH suggested about SteppIR tubes & lengths: Calibrate just runs the motor(s) long enough that the strips can be assumed to be fully retracted & therefore extended from a known state to a known leng
Correction: K4MQG, not K6DGW. Need another cup of tea. Sorry. 73, VR2BG _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTal
K3MH continued: I can't recall the exact shifts reported for which bands, but changing the reflector of a 3-el model on 20m at 15m by 1.5% (I think it was in that neighborhood), the F/B changes more
Took a little while to figure out who started this thread, as very quickly folks are posting responses to other folks' posts... it was WP3C. He asked about a single-boom 10/15/20m beam that would wor
K9RX commented: I would have been happy if they could have posted the bits I needed within a month. Instead it took two months & a bit of chasing by IDD - yet the problems are still not sorted. I tel
This thread has been interesting to watch, though a bit frustrating waiting for everyone to catch up. I see about a 6 volt drop (without or without a motor connected) from the power supply when power
Most Force-12 products are largely just certain lengths of tubing & this is probably why they deal with their manuals as they do. There are now I think knock-off copies of Force-12 products available
N4ZR noted some frequency-dependent variation in measuring loss of his feeders with the 259B, after running some LDF4-50A up his tower. K2XX then mentioned he had seen same (sorry Joe, don't remember
N4UM explained to Tom: Presumably this is with elevated radials? I thought once close enough to ground, radial length determined performance of return currents (significantly reduced beyond where the
N4UM had explained here to "Tom" that instead of using a longer radiator for a 160m inverted-L (then tuning out the inductive reactance with a series cap) he increases the length of the radials inste
AB7E added to my desire to understand how it is possible for the length of radials on the ground to establish resonance of a vertical: Oh, there is no question that proximity to ground has an effect
Or I need new glasses, or perhaps both. 73, VR2BrettGraham/QRT & unsubscribing. _______________________________________________ _______________________________________________ TowerTalk mailing list
