2.4 High Frequency Transducer Assembly
2.4.1 High Frequency Transducers
The pulseEKKO PRO can be used with many different antennas.
Low frequency antennas in the range from 12.5 to 200 MHz were shown earlier (see Figure 2-7).
There are also 3 high frequency, shielded, bistatic antennas available: 250, 500 and 1000 MHz (Figure 2-
19). Each antenna box is really a “transducer” because it consists of both an antenna and the electronics.
The transmitting transducer is indicated with a “T” on the label, e.g. T500, while the receiving transducer is
indicated with an “R” on the label, e.g. R500.
The best frequency of antenna to use on a survey depends on the survey objectives (see Antenna
Frequency, Section 3.2.1: P34)
Figure 2-19: High frequency, shielded, bistatic antennas available for the pulseEKKO PRO. The antennas come in pairs, one
transmitting transducer and one receiving transducer. These are indicated by an “T” and “R” on the labels. The 1000 MHz trans-
ducers are 14.5 cm (6 in) across, the 500 MHz transducers are 22.5 cm (9 in) across and the 250 MHz transducers are 38 cm (15
in) across and all are square.
The procedure for attaching the transducers to the skid plate and attaching to the adjustable tow handle is
described below.
