We need to order ASAP to ship to the south. > > David K. McCarty, K5GN > dkmc@chevron.com Here is what I bought from Texas Towers to upgrade my Cushcraft 40-2CD. We'll see over the next 5 winters if it was worth it. Each "piece" represents a 6' length. Qty Size Cost 4 1.125" 21.60 1 1.875 11.40 6 1.0" 28.80 1 2.0" 11.70 2 .875 9.00 1 .375 2.10 ------ 84.60 + shipping This did the 118 MPH mods specified in the W6QHS article. If you want to save a few dollars and some time, you can skip the small tubing. I am sure it helps, but the real protection comes from beefing up the boom and the center element pieces. Notes: I could not get the driven elements out of the black phenolic. After 7 years the weather had just sealed them together. I ended up sliding the inserts in, after very carefully measuring things, then drilled and screwed them together. YOU MUST DO THIS - Cut the black plastic on the traps and replace the screws that connect the coil wires to the elements. I used Stainless. You can't believe how crudded up this was. I put 1/4"x3" bolts through the boom at each place they joined. Also did the same at the boom to mast plate and at each boom to element plate. I made darn sure nothing was going to rotate this time! I upgraded everything to stainless u-bolts while I was at it. Be sure to put something inside the ends of the boom. I used some heavy PVC pipe. I use a bead balun at the feed point rather than the roll of coax recommended in the manual. Cuts down on the imbalance. Good luck!

Many thanks to those that helped by reply on the 40-2cd W7ZRC,K7GM,KC8MK,W2UP,K5ZD,W8CAR,WB0HRX,KI6IM,AA5ZQ,KE7X,K1FWF,K5GN, AA4NU,KO9Y,K1KP,K5TM, & BRUCE.LEE(NO CALL) ... tried to get them all, sri if I left someone out.... Most said it would tune low when only a few ft off the ground. I did stand the antenna on end with the driven element up and it did tune good that way. (the tower tilts over, so this was in the plan.) The antenna is currently about 30 ft up, used the Cushcraft settings for mid-band and it tunes out very good. Will try it this week-end - higher. Thanks again, this was a very positive thing from the reflector. -- 73 Robert Wood WB5CRG w5robert@blkbox.com
