Design

The BlueFin 2 is a log periodic shark fin antenna with 7 dB of forward gain in a directional pattern. It offers excellent rejection of interfering signals outside of the direction the antenna is pointed.

Transmission or Reception

The Blue Fin 2 is designed for both Receiving and Transmitting. It offers an exceptionally low, near ideal, SWR (standing wave ratio) to efficiently transmit with nearly 100% of the energy radiated. Paired with any wireless microphone or IFB system the range of coverage is almost doubled in the direction the antenna is pointed relative to dipole or whip antennas.

As a receiver antenna it improves receiver operation by eliminating overload from mobile phones, walkie talkies, and other sources of RF radiation.

Paired with a transmitter, the filtered antenna will keep wide-band low level noise below detection levels of receivers that have their antennas in close proximity to the transmitter antenna.

Filtered or Unfiltered

BlueFin 2 can be ordered one of two ways – as a standard BlueFin 2.5, which covers 470-620 MHz or a BlueFin 2.5F which is a filtered antenna with a custom tuned band pass filter of 44 MHz.

The Bluefin 2.5F dramatically eliminates interfering signals outside of the bandpass of the antenna’s filter. These are a custom ordered item that you specify the center frequency of – anywhere from 492 – 598 MHz.

BlueFin 2 Choices:

The BlueFin 2 can be ordered in one of two configurations:
BlueFin 2.5 – covers 470 – 620 MHz
BlueFin 2.5F – 44 MHz custom tuned window at the center frequency of choice (492 – 598 MHz)

A Note on Antenna Amplification

This antenna is not offered with an integral amplifier and we don’t recommend you use one because the background noise is higher than the cable loss the amplifier is trying to overcome. With Zaxcom Digital Wireless an antenna amplifier actually degrades performance because it’s never as good as the built-in front end filter inside the receiver. For the best range we recommend a directional antenna, like the BlueFin 2, with a low loss cable instead of an amplified antenna.
