Invariably when antenna gain is mentioned
questions arise as to gain measurement and accuracy there of.
I do a lot of antenna experiments and declarations of gain never get
any where.
Ihave now purchased a 27 Mhz electric model airoplane and am now in
the process of making a new design antenna and I intend to measure an
antennas
relative gain my comparing the distance travelled by the model by
usind a standard whip antenna and then by using newly designed
antenna.
I visualise keeping a record of distance travelled of my various
experiment antennas.
Does any body see any negatives about this aproach which will always
be done under zero wind conditions? I am looking for a real world
guide to gain to escape from the gain arguments of today.
Thanks in advance

If I'd be allowed to change my mind after I got more thought/information
on this project, I really like the idea. It will be somewhat of an
instrument complex project ?wont it?.
A GPS could record alot of data if the plan includes things like that.
I would have thought that small variations in distance to the aircraft
wouldnt be excessively critical. But, it would be important to keep
records of the angle to the aircraft from the antenna.
I see Excel and some clocks somewhere in there.

This sure would be a fun project. If you do get it working, I'd go to
where you are just to see it in action.
