Re: [Elecraft] Small QRP antenna

With an end fed 1/4 wave you only need a counterpoise that is about .05 wave length. it can be the coax or another counterpoise. Although a counterpoise has some effect on radiation pattern of a quarter wave radiator, it is minimal. You won't see much improvement in performance by going above .

I think this is mixing up 1/2 wave radiators and 1/4 wave radiators. To be resonant, a 1/4 wave wire needs another 1/4 wave "counterpoise" - think of a center fed dipole - it has 1/4 wave on each side whether one side is a monopole (vertical) and the other 1/4 wave is an elevated radial or buri

Re: [Elecraft] Small QRP antenna

Nothing in this post is true. Optimum length for a counterpoise is a quarter wave. Radials are a form of counterpoise, and their optimum length is also a quarter wave. More radials reduce ground losses. Failing to provide an adequate counterpoise will cause the antenna's return current to flow

The number and length of radials determines the efficiency of end fed monopole antennas, how much power radiates and how much dissipates in the ground. That's why half wave broadcast AM verticals have 120, 0.4 wavelength radials. So if you want to keep the fish worms warm, don't use radials. Ra
