Bonjour de Montreal, In an earlier life I used a spectrum analyser and a very special type of antenna to perform preliminary tests before getting to an OATS. The antenna is called a Bowtop antenna. It has 2 advantages 1) it is very small compare to usual (it has a cylinder shape of 17 cm diameter by 20 of height) and 2) it has a very flat Antenna Factors curve (+ 3, +/- 2.5dB from 30 to 650 MHz). The only small problem is that it is an active antenna, so you must recharge it or use it while connected to a power supply.
It is manufactured by a very small company in Arizona, here is the contact: ETA Engineers 3225 N. Forgeus Av.
