Description / M0CVO 1:1 Line Isolator 400w 1.8-54 MHz
The M0CVO Antennas 1:1 Line Isolator operates from 1.8 - 54MHz. It will handle up to 400W CW or 450W PEP.
This is used to prevent unwanted stray RF feedback coming into the shack via your feed line. Banish the interference to the other items nearby radios, telephones, etc.
To use, fix the isolator to a convenient point outside, this could be a tree trunk, fence post, wall, pole or whatever. Attach the coax from your antenna to one connector on the isolator and then attach a second piece of coax to the other connector and use this to connect to your transceiver or ATU.
The insertion loss of this unit is approx 0.02dB so is therefore negligible. It does not affect the SWR / tuning of the antenna at all. If you were using an ATU before, it will still be the same.More Information

Lowered my Noise Floor
Review by
Shayne
My Noise Floor was high on the HF Bands and adding clip on ferrites was just not doing much for me. So after seeing a Waters and Stanton YouTube video about line isolators I did some investigation into what's was out there.
I found a lot of options ranging from £90 to £140 and then when you look at the specs for them they don't cover the frequency range, most were from 1.8 to 30 Mhz. Then I found the M0CVO isolator and found some good reviews and for the money it was a no brainer.
I attached it to the Transceiver end of my EFHW and I dropped 2 / 3 S points on Noise and the difference was night and day, I still wanted more and have bought another one to add to the Antenna Feed point as so many Hams recommend this config to reduce noise.
I have also built a Mains Filter for the power going to my Rig which removes more noise from USB Chargers and next doors LED lights.
You will not be disappointed with this line Isolator and its Made in GB

Ideal if you don’t have time to make one
Review by
Andrew
The line isolator is very well built. A bit pricey IMO for it. It’s ideal if you just want to plug in and play! you can make one much cheaper if you have the time.

Getting back into ham radio after close Excellent product from an excellent supplier.
Review by
Pete G8RXZ
Getting back into ham radio after close on 35 years lay off. Then i was exclusively VHF but with retirement looming ive decided to get an HF shack together. its a while new world of antennas and ATUs and stuff. dipped my toes with WSPR and FT8. an excellent YouTube piece by Peter Waters explained the benefit of Line isolation units and recommended this one. seems great value, is strongly made and good reports elsewhere. as is usual with Moonraker, orders are despatched quickly and always well packed. overall an excellent product from an excellent supplier.

RF Feedback Issues
Review by
Chris
So I use an OCFD with a 4:1 balun. My setup is not ideal with the antenna hooked onto my bungalows gutters, so you can imagine it’s not very high. I was getting RF in the shack, most noticeable on my transmitted audio.
I’ve got clip on ferrite cores on the feed line, mic leads, power leads you name it, even have some of those monster type 43 mix cores that a UK ham recommended that I’d seen a presentation of on the internet and still I was suffering.
Then a local ham said “I think your problem’s will vanish if you get a line isolator” - so I purchased this model, installed it and……..I’m getting positive comments regards the tx audio so I’m well pleased that ????
