I actually did bang away at the key off and on for a couple last eve after midnight...nothing heard or worked. Receiving loop, and flat-top 80 M dipole at 70' with the twin-lead shorted and fed again
Why an "L" versus a "T", with the T's arms over the radials depending upon wind direction? Just curious. Not questioning the design. KH8, some days we can almost see it from Alaska. GL and keep dream
Soldering in wild Alaska/KL7. Two hands and a mouth. Wire supported in one hand, butane/propane torch in other, solder roll in the mouth (don't tongue the contents) with a long lead of solder feeding
Have the folks at Radio Arcala OH8X learned something about 160M antennas and propagation? How has the vert/4-SQ vs Yagi performed? 73, Gary NL7Y _______________________________________________ Topba
As I recall they never blew up the receiver here, unlike TF4M, GM3POI, and others in that direction from KL7 who were consistently available during times of low absorption over the N Pole. Then again
My 160 aerial next season may be a top loaded vert that can be laid over from the base. After fiddling with an "L" at 64N latitude, I'm curious about which portion of the L is best as propagation and
I don't use a PC in the shack out of choice. Spots don't exist. I tune around and work what I hear. W3LPL helps those that use that service. 73, Gary NL7Y ____________________________________________
FWIW, at one point on a 5 acre remote parcel I had a GAP Voyager, GAP Titan, 80/160 parallel Inv-L over 120/125' radials, a 160M Inv-V, a F-12 C-4SXL beam at 54', and homemade vertical fan dipoles fo
One thing I've wondered: are elevated radials more likely to pickup local QRN than those on the ground, or buried? The on-ground 160M loop antennas I've used for reception seemed quieter here than th
In my experience, external insulation (through synthetic covering or frost) lowers the resonant frequency of wire antennas of a given length and height above ground. For example, I typically use 453
The following obs were an annual occurrence until my 85'+ support tree blew down this year. The 160 antenna described below was supported by the tree, and was no more than 4' from the trunk in the mi
Hi Dale and the Topband group. To trim the vertical portion, and return to original resonance every winter, I simply folded the wire closely back on itself in a flat bundle at the feed point and tape
I used eight elevated tuned radials. They angled about 45 deg from about 4' at the feed to ~15' for their horizontal run. To initially tune, I used my MFJ-259 to feed a pair of radials (dipole), then
I've had a Wellbrooke loop for a few years at 20' on a TV rotator. It nulls a single nearby QRN source NW at 300 deg true. EU is about 15-30 deg from here. When 160 or 80 are open over the N Pole, it
Expecting this and given the proximity of my transmission antennas to the Wellbrook Loop (50-100'), I put 10 Type 31 slip-on beads over each end of the RG8-X feed and rotator control cable, and insul
Thanks Tom for the explanation. As always, this is a learning Reflector. Part of my location involves potential BCB, power line, adjacent home electronics, and of course the legal limit transmissions
It's that time of year when trees and temps become Topband topic. Propagation must be poor. Until the supporting tree blew down, my Inv-L for 160 required shortening of the L in the Fall when the sup
Where are the high voltage points in a "T" antenna? I have the choice of putting up either a new T between two trees, or an L again on 160M. The ends of the T would by necessity be strung over and go
Thank you all for the replies regarding the "T" versus "L" rebuild for my 160 antenna. I'm on a 120x120' city lot in Fairbanks. For fun look me up in QRZ, under 'Detail' zoom in for a satellite view
