RadioAlti CBL561 Antenna Review Testing

RadioAlti CBL561 Mobile Antenna Review

In this video, we're reviewing the RadioAlti CBL561 mobile antenna, which can be tuned to cover between 25 to 30 MHz. This means it can be used for either the 11m band or the 10m band.

Antenna Construction and Features

The antenna is made from aluminum alloy and has a sturdy feel to it. It's also pretty chunky, especially towards the base, which is likely due to its ability to handle up to 500W PEP.

Tuning the Antenna

To tune the antenna, we need to adjust the top section, which screws into the middle section. This is done using an Allen key, and it's essential to make sure this connection is as tight as possible.

Using a VNA to Tune the Antenna

We used a Vector Network Analyzer (VNA) to tune the antenna and get an SWR reading of 1.1 at around 28.4 MHz. This is perfect for the SSB voice portion of the 10m band.

Connecting the Antenna to the Radio

Once tuned, we connected the antenna to the FT-710 radio and made several contacts. The antenna performed well, and we were able to communicate with other stations clearly.

Battery Used

We used a bio NA 12V 20Ah 240W Lithium Iron Phosphate battery to power the FT-710. This battery is amazing and ran the radio at 400W without any issues.

Conclusion

In conclusion, the RadioAlti CBL561 mobile antenna is a great option for those looking for a reliable and high-performance antenna. Its ability to handle up to 500W PEP makes it suitable for use with high-power radios.
