[KL7AA] Getting Started on HF - Looking for Antennas

[Adam Booth]

Hello!
I am just getting started in HF.  I am currently working on my
General so I won't be transmitting but I am more of a listener than a
talker anyhow.  It seems like a good place to start is maybe the 20M
band.  Are there any bands that you would recommend for a beginner?
 I don't yet have the cables to work digital but I would like to try
that in the future as well.  I am also looking for any
apartment-friendly 20M or other HF antennas for sale -- I know that
finding an apartment-friendly HF antenna might be a tough find so I
would also be interested in something I could set up outside
temporarily and I could work outside during the summer, I'm thinking
of maybe setting up in Kincaid Park or somewhere higher up.
If anyone has any recommendations or HF antennas for sale, I would be
very interested.  I'm also interested in any and all Yaesu FT-817
(non-ND, although I think ND accessories would be compatible)
accessories up for sale.
ThanksAdam BKL3TX
