1280 V antenna range

What is the difference in the signal strength on a typical VTx V antenna? front to rear, how much actual distance does it generally mean? Of course I'm considering facing the V toward the tail and I'm trying to determine the value.

The open end of the vee has a bit better transmission than the pointy end. Therefor its recommended to have the open end towards the nose of the aircraft so you dont lose signal after you've turned around.

The reason is polarization. Te Vee has no balun on it and therefore it will tilt slightly in favor of the open end of the antenna. Range difference is imperceptible.
