An integrated via-hole balun is used to feed the antenna …
A dipole is quite easy to construct. The length of a half-wave dipole might be thought to be the same as a half-wavelength of the signal in free space, but this is not quite the case. A number of effects, including the velocity factor of the wire, the length / diameter of the wire used for the radiating element and … Se mer It is easy to construct a dipole. Basically it is simply a half-wave length of wire cut in the middle. Typically it may be set up something like Fig 3. While this may be the ‘standard’ type of installation, rarely is it possible to make an … Se mer The maximum radiation from a dipole takes place in the centre. Accordingly, this is the most important area of the antenna to keep as high as possible. Coupled with the fact that in many situations it is only possible to have one … Se mer Nettet23. okt. 2024 · 13,888. Location. So Cal - Richardson, TX - Tewksbury, MA. Jun 23, 2024. #3. In my experience Hamstick dipoles can work ok on 20m and up but on 40m and below forget it. They are too small to have much efficiency on the lower bands and will be very close to the ground causing more problems.
