What is a coax trap?

What is a coax trap?

What Is a Coaxial Cable Trap? We can define it as a parallel tuned circuit or PTC. So, this is a capacitor placed in parallel with an inductor. You choose a resonant frequency. The PTC is inductive at all frequencies below that one.

What is a trap dipole antenna?

The trap dipole antenna uses a parallel resonant circuit or trap, that resonates on a particular frequency, thereby isolating a section of the antenna. This enables the inner section of the antenna to be used on the frequency where the trap resonates, and the whole antenna where it does not resonate.

What is an advantage of using a trap antenna?

3-63J4: What is an advantage of using a trap antenna? It may be used for multiband operation. It has high directivity in the high-frequency bands. It has high gain.

How do you test antenna traps?

“Grid-dip” meter method A simple way for the determination of the resonant frequency of a trap, or any tuned circuit is to connect a small section of wire forming a close loop, connected to the analyzer test port extension cable and put it near to or around the trap; see the Figure 1.

Why choose Hi-Z antennas?

Hi-Z Antennas has been producing excellent low band receiving systems for many years. Hi-Z’s focus on improvements to low noise components and array systems has… Hi-Z Antennas has been producing excellent low band receiving systems for many years.

What is Hihi-Z?

Hi-Z was coined to be synonymous with high impedance. Z is the accepted engineering term for impedance. The specialty at Hi-Z Antennas is signal processing from shortened vertical antennas which reflect very high impedances at low frequencies.
