Okay, here's the situation:
I moved, I took my tower with me, and just poured and set the base into 10,800 pounds of high strength concrete. (4'x4'x5') So, I have 45' to the thrust bearing, a Yaesu '800 SDX rotor, and a TH3JR so far. I have four 10' copper ground rods pounded into the bottom corners of the hole and double clamped to separate runs of 2/0 copper running up each corner. The rods and cables were covered in clay before the pour, so they are not encased in concrete but rather beside it so as to not have it split in the eventual occurrence of a strike. (I live on some of the highest turn in the city.) Anyway, I have the TH3JR for HF, and I will use a G5RV for 40/80/160. I bought the TH3 a few years ago and its been stored in the garage attic for a few years. All feed lines will be 9913 and 9914 except for the 23cm feed which will be 7/8" hardline. I am in a city, and the tower is 10' from the lot line, so I have to keep it reasonable. Above the HF, I wish to mount a multipurpose yagi. I'm looking at two antennas from Cushcraft: The A6270-13S (6m, 2m, 70cm beam, 5V elements on 2 & 70, 3H elements on 6m) and the ASL-670 (6m, 2m, 70cm log periodic, all in one plane, V or H as mounted.) Anyone have experience on these units? Above this will be a 900MHz yagi, and finally at the top of the mast will be a Diamond X-6000 or X-7000 for my local 2m/70 contacts, and the 23cm for the repeater which will be housed at the QTH. So, back to the multipurpose Cushcraft... anyone love/hate either of these? Any other suggestions on what to install or avoid? Thanks! Pat, VE3PMK |

hey pat
i have heard several of those cushcraft yagis on 6 meters and they do okay guess it all depends on what you want to do with the antennas if you want to do SSB on 2 and 440 then the log would do you better cause you can have them all horizontally polarized if you want to use VHF/UHF for FM and SSB on 6 i would suggest getting the yagi now if you want to do FM on 6 i would suggest getting the comet GP15 which covers 6-2-440 for FM and get the Log for SSB good luck |

Make sure the 9913 (I don't know about 9914) is run so that if water gets in at the antenna end, it will drain back out the same way. Once 9913 gets water in one end, it WILL act like a hose, since it is semi hollow on the inside. The 9913 FLEX is OK. Tam/WB2TT |

9913 acting as a hose!
Good point, I'll make sure all feeds go up a few inches before looping down. EXCELLENT SUGGESTION! Thanks! PS:9914 is just like 9913 except the dielectric is solid foam, no teflon/air helix, therefore more water resistant.
