We just made a range dipole for 900 MHz. The balun we ordered from
Minicircuits (pay careful attention to pinouts) was a 1:1. It resonated
well once we took into account that the polyethelene mounting block
imparted a velocity factor which shortened the rods slightly.

Hi all.

This may seem like a fairly basic question. But here we go!

I want to performance test a 436MHz high gain antenna. My plan is to
construct a simple dipole with a 1:1 balun for 436MHz as a reference antenna
and construct another dipole with a 1:1 balun to receive the test signal,
measure it with a diode detector and a milli-amp meter (field strength
meter) at the shack. Do the calculation and have the antenna gain.
This seems to me to be fairly straight forward, but has anyone carried out
similar measurements and concur with the approach or are there are there
traps and pit falls that I need to be aware of. Or is their simply a better
way?


Cheers
