no, but I built one of these:

it was pretty decent, for that type of antenna anyway...73, W5XZ, dan

Flex uses a similar antenna, a PIXEL Loop, at various Hamventions around the Country to demo their Flex 6XXX radios.  Maybe Tim could elaborate on how well it does or does not perform and that will give you a good idea of how a Wellbrook loop will perform with a 6300.  I plan on using the Pixel on a Flex 6300 but have not ordered the radio yet.  (X-mas gift from momma :-) )

The Pixel loop rocks!

I use a Wellbrook loop for the lower bands and it works just great - I use a PTT line to control my little control box to switch power off the loop when I am transmitting on my vert. wire in a tree.  I live in a very restricted area and so everything is low-profile (I painted the Wellbrook with camo-paint.)

I have heard the Pixel works good too, so do your research and make your choice !

How has your Wellbrook been holding up for you Walt? Do you use it for diversity reception? I'm considering purchasing something from their lineup.

Oh - I have a 6500 . . .

+1 for the Pixel. It doesn't have enough capture area to be a great performer on 160, but for 80-10 it works pretty darn well. I have one on a rotator about 8 feet above the ground.

I also have a Pixel Pro-1b about 8' above ground level.  When there is a lot of noise on the low bands in the summertime it is amazing.  A noise floor of S7 will usually drop to S2 when I switch RCVR to the Pixel.  On the other hand, when the bands are full of signals around S3-S4, when I flip on the Pixel they jump up to S7-S9.  (It lowers the noise floor but amplifies signals.)  Use of the interlock is a must - the Pixel preamp is switched off when any transmitter goes into transmit.  Yes, the loop is small, but thanks to the 30 dB preamp in the antenna it is not just another loop.  Also, the very deep, very narrow null off each side (3-4 degrees wide) is occasionally useful to null out a source of interference.

I use the newest ALA1530LNP Wellbrook loop with my 6300 together with a MFJ 1026 - just wonderful! The Wellbrook is 150m away from my house on a hill.

I assume the Wellbrook is receive only!

I've been using a Wellbrook loop with my 6500 for about 2.5 years - it works very well. I live in a relatively quite area noise-wise, but do get some noise from nearby solar panel inverters - rotating the loop makes it virtually inaudible.

It's on a cheap rotator about 2m above the ground, about 20m from the house.

This is an interesting thread.  I've often wondered how these small receiving loops work in comparison to say a (low band) dipole at 25-30 feet.  At one time I did some reading on them and came to the conclusion that they were mostly beneficial to folks who lived in an area with high noise.  The loop was then used to null out the noise and make reception possible.

Reading this thread, I'm getting the impression the loop actually may work better than a dipole at 30' even in a somewhat noise-free environment.   Is this true?

Is the loop low angle or high angle or a mix?

Norm, I just purchased one and like you I was a little skeptical. Installed it with a rotor and believe me it works very well. In my area with no signal the S meter noise reading is about an S7 with the mag loop it's S2. Weak voice signals are easy to make out.

That's what I was expecting Bob.  The thing that I don't understand is how the loop works in a situation like mine where I have very little man-made noise.  As an example, my dipole on 40m is usually sitting between S2-S3 and seldom up to S4 or S5.  Atmospheric noise on the other hand can get pretty bad during the monsoon season.

Will the received signal on say 80m be stronger on the loop than say a 80m dipole up 25-30 feet?  Once again, most of the time I have very little man-made noise but like everyone else there is the typical atmospheric noise.

if you model it in EZNEC, it's an rx cloud warmer...

Norm...I purchased a WellbrookALA1530LNP-2 last August...it is up ~ 20 feet on an inexpensive RCA Model VH226F rotor...works beautifully, particularly on 80 meters with lower noise on 80 - 40 - 30 - 20 meters than my Mosley 67C beam up ~ 50 feet for 40 - 6 meters or an inverted 6-inch diameter, 6-wire "cage" inverted V up ~ 45 feet on 80 meters...generally signal strengths are higher with the beam but the drop in noise floor from beam to loop of two to four S units usually results in a higher S / N ratio in the loop vs. the beam or particularly vs. the 80 meter V antenna...loop is on a 2 foot mast above the rotor and is very sturdy...no complaints...

Norm, just to clarify, I purchased the Pixel from DX Engineering. Parts, if needed would be less problematic here in the USA.
