Thanks Chris and Steve I assume I should avoid the eBay devices as they could be fakes? could I buy a couple from you Chris as I assumed you go to one of the big suppliers and I want to avoid their Mo

Hi Steve, The active device is an Infineon BFR106 transistor. You will be OK using 75 ohm coax with it without modification. What appears to be an output transformer is actually a common mode choke to

Hi all I have a CCW beverage preamp and I suspect I have accidentally put too many volts up the coax from a variable power supply. I was trying to see how much voltage drop there is in my 400m+ long c

I’ve had my new CCW LAA++ for a number of weeks now and have given it an initial test drive. Ordering the loop from Chris was easy and problem free with the package arriving in a reasonable length of

On the terminated inverted U web page it says Can I run an extra wire between the two earth or ground rods?... I've now tried this and while it increases antenna efficiency by not including the ground

Hi, Sorry for the newbie question but on the LAA++ is the null area the hole in the middle of the "doughnut" ? So just to check my understanding the antenna is picking up broadside.. is it a 360 patte

Hi all,just out of intrest does the cross country bias t work on wellbrook loop? regards

Chris, I received the double loop antenna with bias T in today's mail. Looks like a nice item. Hope to try it out in next few days. Thanks Paul,WD8OJL

I've found a 10 foot section of electrical conduit that can be bent to a circle. (extra conduit will be cut off) Trying to go for something like this... (see picture) My question is, does it matter if

Hello, I am looking for an BNC male connector to fit my MedaBridge RG6 Quad Shield coax to use on my LAA++. I've purchased one of those "screw on" types but it doesn't fit my coax but it will fit my R

Hello, I've just purchased the Loop Antenna Amplifier ++ and I have no clue how I should assemble and power it. Only thing I've figured out is the bias-t needs 12V, okay so I need to find a regulated

UK Users of the CCW Active Loop Amplifier ++ may find my design of an aluminium loop and the use of a 9V Battery Box of interest...People in other countries may be able to source similar materials to

Thanks very much for the help,iv gone back to using the wire that came with it.its working better than the coax loop. Regards

I've just added a YouTube video on the new loop antenna at the bottom of the web page: https://www.crosscountrywireless.net/active_loop_antenna.htm It shows a quick table top review and demonstration.

Hi all,can I reduce the gain on the loop by using a smaller loop say 2meters? Regards

Hi All moving very soon we hope ( on going for 6 months!!!!) to Bittaford, Devon from Dagenham, London.. big changes bigger garden! antennas here for low bands are mag loops..work well considering 5 b

We have just started building the first production batch of the HF Active Loop Antenna v4. They will be ready for shipping in about a week. The antenna uses a small double loop 350 mm or 14" in diamet

Good afternoon Chris. I have your VLF/LF/HF Active Vertical Antenna and noticed of late the base unit red LED showing connection to the amplifier doesn't immediately light when the unit is powered up.

My compliments to CCW: Today I once again received the historic Alexanderson VLF transmitter SAQ in Grimeton Sweden on 17.2 kHz very well, with snr > 30 dB. Antenna was a triangular wire loop of 5.4 m
