Cross Country Broadband Active Antenna

Postby Mitch » Sat Aug 26, 2017 6:48 pm

Hi everyone

Just purchased a AR-DV1 and a Cross Country Broadband Active Antenna.

I'm hoping this antenna will do a good job.

It's expensive however I will produce a complete review of its performance, if anyone has any suggestions on what they would like to see in the review let me know

Active antennas are a reasonable compromise if you have severe limitations on what you can do. But they do NEED height to work at their best, it's called close coupling & that reduces with frequency, so at say 7 mhz you really need the antenna to be at about 3 to 4 floors high, but at 20 meters, a bungalow chimney should be fine. Also they need careful coax routing to stop extra noise being picked up.
The active part of the antenna is probably a pre amplifier & knowing Cross Country a well made one that will do it's job well. But it will be interested to see how it performs for you.
What are your limitations? As a wire does not need to be long & is much less visible than a small loop type antenna.
Do you know how directional it is?
Edited to add. I would also be interested to know what coax they recommend & if they suggest the use of a common mode choke or have one built into the design. My reason for asking is that 75 ohm coax gives better signal to noise ratios than 50 ohm & 70 Ohm satellite coax also often has a foil screen around it, which again can help with noise levels & a choke would again help with noise levels.
