Here is one "else": Quarter wave "bazooka" coax balun increases the bandwidth. Change in its reactance with frequency works "against" reactance change of antenna with frequency. Yuri, K3BU List Spons
Huh? Where did I say anything about antenna elements? Thicker more lossy conductor (same material)? Hmmm! Tom is "right" even when he is wrong, I rest my case (again :-) Yuri, K3BU List Sponsored by
You din't get it Tom, we are not talking about "Bazooka" dipole, but Bazooka quarter wave coax balun connected to antenna and fed with coax. Read my first posting and K7GCO explanation again. I got i
Tom, Nice try to dance out of it :-) Who is talking about coaxial dipoles? So it worked for some 50 years, now you "calculate" it doesn't? 73 Yuri, K3BU List Sponsored by AN Wireless: AN Wireless han
K3GB, The usual scenario is, one gets interested in ham radio and antennas, so the exploration and learning process starts by getting the "bibles" like ARRL Handbook and Antenna Book. There is enough
Feed the coax through the water hose, put connectors on it, submerge it and enjoy! Yuri, K3BU List Sponsored by AN Wireless: AN Wireless handles Rohn tower systems, Trylon Titan towers, coax, hardlin
wires The ideal thing to do, cover the largest area with grid you can, you will have close to perfect ground for any antenna, especially vertically polarized. GL Yuri List Sponsored by AN Wireless: A
with I designed 3 el. Quad on 2m model, scaled to low bands had no problem, no tuning necessary, wide bandwidth, 50 ohms impedance, no matching, no stubs. That was for single band (20m version had 30
Rich, Where was it fed? Your last sentence implies it was fed horizontally (like a dipole)? In that case your statement is true, quad loop behaves like the horizontal dipole. I have modeled quad loop
When storm is coming, just drop the sucker down, you need it for safety in case the wind comes up. If you nest the tower down you will have enough contact for any possible lightning strikes. Just gro
Not verified, but speculating that steel wool (after a while) would act as a bunch of diodes (corroded junctions), rectifying RF currents and generating harmonics. For monoband entennas I preferred 1
I had second hand Gem Quad spreaders, after few more years nasty thing happened, the fiberglass rods started to separate from the criss-cross wrapping and eventually buckled in the storm. I would rec
Much better pattern, more gain, rejection and RX performance (S/N discrimination). I tried various 3 el. configurations, they were inferior to 4 sq. Yuri, K3BU List Sponsor: Are you thinking about in
Maybe I missed something, but what about using simple trap? Trap isolates or "disconnects" rest of the radiator above trap. They can be made efficient. The disadvantage is they are frequency specific
snipididuda.... Hmmm, and narrower antenna pattern has nothing to do with (longer) boom length? Some contradiction going on here (again). Isn't it a bit farfetched to compare stacked dipoles (zero bo
Why didn't I think of that! While people are arguing about SO2R, I am trying to figure out SO4R on the same band. Two radios on different bands is chicken feed. Must be hard for RF scrambled brains t
Talk about concealed antenna! Got one, loop burried around the property perimeter (abt 700 ft), about 1 inch deep, using it for receiving with good preamp. (Sucks on transmit :-) It was supposed to b
I will take the bet! I never had wire fail in Quad from flexing. There is (almost) no flexing when antenna is properly strung, with just enough tension to keep the wires from flopping or flexing. In
Interesting that W4RNL is claiming that Quad loops have HIGHER Q than a Yagi (halfwave) elements. I was led to believe by W6SAI and other's claims that Quad loop has lower Q. That is what I reasoned
