Recent forays up to the thin air at 1090 MHz and the requisite web-surfing have made me aware of a new antenna analyzer that is reportedly accurate and inexpensive for what it offers.
Enter the N1201SA Vector Impedance Analyzer. A 140 MHz to 2.7 GHz range and a price tag of $165. An online manual is here (3.2MB pdf).
Separating it from most other hobby-type analyzers is the addition of an S11 port. This makes measuring line losses quite easy.
A very favorable comparison (in German) with an Agilent analyzer is made here by DJ3LE.
Another reviewer demos the analyzer on YouTube:
Besides ham radio use, this gadget may appeal to those who use radio control or tinker with improved antennas for wireless routers on 2.4 GHz.
