disconeStrip
Description
The disconeStrip
antenna object creates a strip discone
antenna. The strip discone antenna is an approximation to a solid discone antenna, where the
cone and the disc are replaced with strips. The strip discone antennas are lighter in weight
and suited for applications in high frequency (HF) and very high frequency (VHF)
bands.
Creation
Description
creates a strip discone
antenna with dimensions for a resonant frequency of 147.38 MHz. The default strip
discone antenna has a feedpoint at the center of the disc.ant
= disconeStrip
sets Properties using name-value
pairs. For example, ant
= disconeStrip(Name,Value)disconeStrip('NumStrips',8)
creates a discone
strip antenna with eight strips. You can specify multiple name-value pairs. Enclose each
property name in quotes. Properties not specified retain their default values.
