Yes they are good but no moor than 30 watts into it .the only thing I
Do not like is the LEDs are a bit dull but other than that good you will need
Thick cable andi use a 60 amp psu.

The amplifier is a decent one, make sure you use a good quality coax,i would suggest using LMR 400 and in 3 foot increments (30 feet,36 feet 60 feet, 120 feet, you get the idea) to stay within the correct wave lengths.

Coax length shouldn't make a difference.
Can of worms opened lol.

Hi Dave
All set up now with the bigger power supply...
It's alot bigger in size compared to my. Kl03 ,the biggest piece of CB equipment I own lol...
It does get out well though glad I bought it..
Think I could have got away with a 50amp power supply as it only draws 48 amp at full power
Overall I'm pleased with it..
Havent been using it the last few days as I have been banished to the shed with my radio equipment and it's really hot in there with this weather ....
All the best
