Radio Frequency (RF) & Wireless Design

The dipole at 74 ohms impedance is the second most common form of antenna next to the vertical monopole :

But for those wishing to save space opt for the folded dipole which increases the impedance 4 x to 292 ohms impedance :

However, those wishing to save even more space will opt for the circular curved folded dipole known as the halo antenna :

I have re-created my own version based upon a commercially available one with the intent to improve performance by reducing any ferrous (e.g. iron, steel) magnetic components such that the antenna radiation pattern is optimized :

2m Amateur Radio Halo Antenna

This is a model of a 2m Amateur Radio Halo Antenna that i designed after a commercially available one wherein i made modifications to remove all ferrous materials to help improve the performance of the antenna. https://www.amazon.com/FM-Loop-Antenna-Outdoor-Attic-mount/dp/B006SLV25C/ref=asc_df_B0...
