ZA-048 logarithmic periodic antenna, dipole array spectrum analyzer accessories, receiver search signal

ZA-048 logarithmic periodic antenna, dipole array spectrum analyzer accessories, receiver search signal，used for ZS-407 

Delivery packaging carton size: 30*30X4CM

Net weight: 340g/set

ZA-048 antenna is printed with LDPA.

We have used some optimized design techniques to significantly reduce the size of the antenna.

Now it can be easily used with tinySA ULTRA.

With new technology, we can now use a resolution of 27x23cm.

Match the ultra-wide range of 400MHz-8GHz,

But it will lose some low-frequency directionality.

The rated input resistance of the antenna is 50Ω,

When the antenna is connected to a 50Ω source, the return loss will fluctuate.

In most frequency bands above 1GHz,

The return loss is about 10dB or lower, and the VSWR is about 2.

In the 400M-1GHz frequency band,

The return loss is about 4.5dB or lower,

and the VSWR is about 4.

VSWR increases rapidly at frequencies below 400MHz.

ZA-048 can be used for radio direction measurement

at 1GHz-8.5GHz frequency without strict requirements.

When held with one hand, it is quite sensitive

to the direction of the signal source and changes direction with the body.

We design it to be as low-frequency matching and orientation as possible.

However, due to the limitation of antenna area, we had to lose some low-frequency direction.
