You build a 1/4 wavelength groundplane antenna
L'antenne colineaire
All elements are connected to the boom directly NOT isolated from the boom, you may mount them on top of the boom or trough the boom
L'antenne Lindenblad
The Lindenblad antenna has ideal features for receiving transmissions from moving satellites during very low passes on the horizon.
Laptop Mini Wireless Antenna
The size was chosen so it could be housed inside the tube of an old pen, to provide rigidity and protection to the antenna
