Hi Guy,
Of that would be of any help here is a list of parts I used:
PVC IP67 box: (different sizes available)
Cable glands: (PG25 is a
bit wide for CAT cable that goes down to receiver, so either some
silicon self-adhesing tape can be used or PG19 just for the cable
entry)
Clamps that I used on the back of the box:
(U-Bolts were replaced with straight 5/16 bolts)
Straight bolts:
(not really sure if they are high quality SS, but I didn't care much
for this application)
I also used 5/16" wide fender washers from the inside to hold the
bolt's heads. Plus a good amount of heat glue (good silicone should
probably be better).
Mast:
(not as strong as other expensive ones, but we will see how it will
hold up and I only used 3 lower sections. Sections glued together with
epoxy to prevent collapsing down.)
CAT8 SFTP "heavy duty" outdoor rated 25ft patch cable used to connect
antenna to LZ1AQ control board:
.
I put quite a bit of FT240 toroid's on it to fight the noise and
interference at my Urban location (2 at antenna, 3 at control board
and 1 in the middle of the cable).
Tripods I'm using at the moment:
7/8" copper pipe that I used with another loop and decided not to use
with this one due to it's weight:
5/8" aluminum tubing (not from these sellers but very similar item):
!94040!US!-1&itmprp=enc%3AAQAJAAAA8HoV3kP08IDx%2BKZ9MfhVJKnbBHv4DsF7CvTgz%2Fz2seoNNj1Z0J7XLn4m6xDiZ%2FZvf95r9lIDbMA14Yc5PbKP1vRNd47P6lfVeox4SSjm8G2Rspck0p1YQwOasqBofv00QB%2BWrOCyLvHBGinLqBZz2ZTTi4e4y4KaMduJmBrs8Y79uBvdc9YZ7F6Z69vPOILYYPQYkI8jSc8EoFvegz5NwI0MHC1KnloljYZ5XT%2BjDdBMVwaF7jSQNSihbzZrpkz9JFpKmgck3tOoUWNuvTktZ%2BET%2F6WLzvXAVThswPcc36l6sBKmiHJpBEkwyfEiyMyeZQ%3D%3D%7Ctkp%3ABFBM5K7q86xk
Both 7/8" OD copper thin wall tubing and 5/8" OD aluminum tubing are
thin walled and can be formed by hand - no roller is needed, just time
to make it more or less round shape.
But as I mentioned before if I need to redo it I'd probably use 1" OD
PEC-AL-PEC instead.

Hi WN4ISX and Simon,
Thanks for the notes. Both of you.
First WN4ISX (Terry?) Thanks for the reminder to keep notes. Being an old submariner and Sonar tech, ELF,VLF,HF and NDB's and CW interest me. Loops too as putting up high wires is next to impossible.. Everything from ground or my wife watching me stumble around on the roof on my butt (HIHI) and thats after climbing the ladder!. Canes and roofs are not compatible. Sons are non existent here in the sticks. About clubs.. long story here.. went a couple of times, mostly (if not all handy talkie stuff). I even brought some homebrew stuff (recievers,qrp HF and more) they looked.. said wow and that was it.. I even got an IC-910H with all the bells and whistles to see if I could interest them. All I got was being approached after 3 meetings to run as president of the club.. nah.. my health not acceptable.. but my desire was there. Many said they would come visit to see my setups.. but never came.. a non starter.
EMI.. well the 20,40,80 bands are noisy.. I have a lower 240ft doublet, home brew up about 60ft.. that took me 2 weeks to hang.. and a home brew 80m efhw ant with 49:1 transformer again homebrew..
Its loops and technical things for me now. I cannot find anyone interested in this here in the rural back woods..
Simon thanks for the info on the PEC-AL-PEC 1 and pictures of your implementation. This is almost exactly what I wish to do.. except, if possible, off the ground. Using and anchored tripod or pipe in the ground with cement.
Good Morning to all
Guy N1GMM
