Can I have multiple inverted-vee antenna fed by a single coax?
A friend who recently received his call is planning to setup an inverted-vee for 40/20m bands. Our take is the signal will take the path of least impedance into the correct length antenna wire.
Something like the image attached; it depicts two wires…

How does aluminum siding on a house affect an inverted-vee antenna next to it?
My two-storey house is wood with alumninum siding. I had wanted to install an inverted-vee antenna with its midpoint hanging from the eave, and endpoints near the ground, but this would place the wire of the antenna about a foot from the siding. …

How to measure wire for antenna leg | 40m inverted V
I am building the antenna for the first time and I have choosen to start with 40m inverted-v. I am almost done with the center insulator made of PVC piping elements, three eye hooks and SO 239 connector at the bottom.
Now I am getting ready to…

How much distortion would aluminium wire stays for the centre-pole on my inverted-vee cause?
I used nylon rope from the nearest hardware store to stay the centre-mast on my inverted-vee for the 20. The centre-pole is a long long looong bamboo. The trouble is rain here really isn't friendly to nylon; a year - 2 years at most.

What is an expected SWR plot for a trap dipole?
I've build a trap dipole for 20/40m bands. Traps are made of a coil wound on an insulator of RG213 coax and 3 kV NP0 capacitors. The impedance measured with EU1KY antenna analyzer is following:
This is a single trap, before and after putting a…

Raising height of inverted V by 2 meters
Now that I have a working G5RV Jr. and have had some good luck with DX (Croatia and Venezuela on 20m, Morocco on 40m from Michigan at 100w output), of course I want to mess with the configuration. It's sort-of an inverted vee at about a 145 degree…

Can you use elements of fan inverted V for guying?
Diagrams of fan inverted V antennas usually show the elements quite close together and parallel.
Anyone experience of, or insights about, spacing elements at say 90° or 120° around the tower to guy it? Would plan to keep the two elements of each…
