Have not measured elements yet but remember this is cut for 10 meters so we need to do a little calculation to compare. The Flexible stub wires are 147.5" ?? which differs from Harvey's 128", the brass stubs are the same at 18".

Yep, will do.

Ok, got it. Thanks Didn't notice any set screws, probably lost them already;-)

I hope to have more time later today to reread everything and post the manual. I'll be sure to take some photos to share as well. Thanks for all the help!

Marconi and group, I received the L4+ today and have just unpacked it. First impression is that it was nicely packed and well organized with a clearly printed manual. It looks very professional. One of the first things i want to do is measure the wires. Some have recommended stretching the wires...

Thanks that eases my mind.

I'm thinking of dropping it down some to reduce all stresses but I'm wondering how far I should I keep the bottom of the quad from the 2m yagi below it any ideas?

Removing the other 2 beams is not an option but I will leave my wire antennas down while I tune it. Is there any reason I would want to use a choke besides cost and weight?

That was my point. :-)

I have attached an attempt to model the mast stress with the 30' quad, 2m yagi, and 2m vertical. 40' quad max wind 93.39mph My current proposed array with L4+ 75.33mph Might need to bring it down a bit. Is ~80 mph a reasonable goal. You can't plan for everything, we just had a tornado hit about...

Great info JJ, I think I will do mine the same way with the spreaders. 1st thing I'm going to do is measure the wires, if I have a problem with breakage (I hope not) I will replace them with something stronger if I can find something better in 13 gauge which is what it is designed for. Thanks...

Yes, you have it correct and I understand the concern regarding all the stress at the rotor/Voyager hazer. The rotor is inside the hazer so only about 2' or 3' of mast is below the top of the hazer. The top section of tower is 8' and I have 3 guys, steel cable at 30' 1/4" phillystran at 50' and...

That seals it, I'm not putting anything above the L4, why put up what I consider a high performance Quad and then mess it up with another antenna. Thanks so much for the models! The weight will be minimal and I agree the vertical support will be worthwhile especially if I add a couple of baluns.

This is very interesting. It looks like the choke improves the gain both with and w/o the iMax, have I got that right? I really believe in chokes, the only reason I didn't use one on the iMax is because it is temporary and I wanted to see what it would do. I built a simple CMC meter this weekend...

JJ thanks for the input, you make some excellent points. I have also heard that the spreaders wear from movement in the mounts. I was thinking of using silicone of some sort to eliminate that as someone else posted somewhere. Did drilling through seem to weaken them? Sounds like the spreaders...

Hi CK glad you asked this gives me a chance to double check the numbers. First 10' out of the tower is where the 20m and 2m antennas are mounted. It is 2" with .25" wall. Don't know the exact specs because I bought it used but I'm guessing it is at least 95,000 yield because it was holding up a...

Good idea, I think, but what should I be praying for:-) Do you have any ideas about the effect of placing my iMax 2000 above the L4+? I've just about decided not to do it because of mechanical reasons and I don't want to take a chance of altering the pattern. What do you think?

Hello all, I pulled the trigger on a Lightning L4+ today. I'm looking for input as to whether it is worthwhile to try to put my iMax above the quad. I can probably get it a maximum of 3' above the top of the diamond but I don't want to take a chance of deforming the quads pattern if this is a...

Thanks for the input and sharing your experience, it is very helpful and encouraging.

Marconi, thanks for your personal response to my inquiry. I appreciate it. I have been thinking of putting up a dual polarity quad for about the last 4 years but have been sidetracked for several reasons. I am almost convinced that this is the best option for me. Even though I have never seen an...
