Is VPN enough to hide IP?

[Lauda]

If the whole area was flat with no buildings that would work. Penetrating from the middle of a city to reach 20km? I highly doubt that.
Although I did not know about this Antenna ty.

If you are on top of a tall building in a center of a city and no interference it will work.

Yes, everyone lives on top of the tallest building.

But keep in mind that such popular, free VPN service will release your real IP on every request  

Yes can't believe any free vpn service better to spend few dollars and buy premium VPN service to secure your data there are many cheap VPNs available to use it with better protocols. I would suggest read some vpn reviews such as IPVanish.com IronSocket.com etc...

Go buy a list of proxies and get elite proxie switcher change your ip on just a click.

For skype there have many methods of hiding your self... One don't file transfer/talk to anyone you don't trust with out a vpn on. People on twitch learn this real fast.
