Very nice study and IMO neither small nor inelegant. Thanks I just did a small and inelegant piece of modelling with EZNEC. I took a wire 128' vertical, and it showed a gain of about 1.7dBi over a pa

Well I applaud your making the effort at giving an "honest" report. It seems to me that 599 is reported far too casually these days and I certainly attempt to give "honest" reports even in a (non con

43. Topband: Fw: Are stacked verticals feasible? (score: 1)

Say Paul I am going to try the same setup except ground the 80m vertical as a close (5') coupled radiator and see what the feed impedance of the 160 vertical is on 80. It models well... I don't know,

45. Topband: arriving wave angle (score: 1)

Hi although I can visualize a transmitted 'wave angle' as the elevation of peak field strength, and its relative strength at other angles forming a "lobe" - what is the situation for sky wave signals

Hi Bob thanks for the reply. My question wasn't as clear as it could have been so let me try again. Say we have 2 stations with isotropic transmitting antennas and receiving antennas with good angula

It's certainly a nice setup. WITH SUNSPOT ACTIVITY NEAR ZERO AND THE SOLAR FLUX 'WAY DOWN WILL TOPBAND COME OPEN? http://www.swpc.noaa.gov/rt_plots/xray_5m.html _________________ Topband Reflector __

Hi I just heard from Peter HS0ZKX now QRV with 500W to a vertical and a couple of reversible beverages, and he reports top band is open to the East coast around 1200Z. And he's an easy QSL! GL 73 ___

Yeah DXCC stopped being interesting for me back when the the UN HQ building in NYC was declared to be a "country"; maybe it isn't even on the list anymore I haven't checked for decades... On Tuesday,
