Hi everyone,
Apologies if this is slightly OT but I am new to gnu-radio, radio and SDR.
I am interested in what people are doing for antennas, I was thinking
that some kind of modular antenna would be cool, basically an SMA
connector, some cable, a groundplane with a hole to slot the antenna
in to, you could then change the actual antenna piece for different
frequencies, no doubt I am missing something fundamental?
So my SDR has a frequency range of 300MHz - 3.8GHz, so you could have
20 pieces of thick wire (your antenna), each one a different length.
Thanks for looking.
Cheers
Richard
THere are a number of antenna designs that are broadband.
The discone is the most classic, and there are Log-Periodic Dipole
Arrays, and log-spiral antennae, and a number.
You should probably exercise your google-fu and see what you might be
able to have a go at building yourself.
But, yes, having a "library" of 1/4-wave antenna stubs is one way of
doing it....
