I have a 10 20 40 75 meter 25$ mobile hamstick on my balcony.(use a good tuner) These work good for the price. I use a vice grip mount, they seem to be better than a mag mount.
All I can say is 10 & 20 is fine, but 40 & 75 have problems, you cant get a good ground 3 stories up.
Dipoles won't work, I’ve tried don't waste your time.
The MFJ artificial ground is a must if you want to work the higher freq. The longer the antenna the better, don’t be fooled with all the balcony scams.
You will spend a lot of money and be no better off.
I'm still looking for something better and if anyone knows of something let me know
