This is K1GU, NedTN’s Moxon setup- 4el Steppir below.<\/p>\n

The Moxon elements are just under 50′ long while each of the 4 ‘T’ elements are about 20′ long.<\/p>\n

The Moxon Boom length is about 22′<\/p>\n

For size perspective, the lower 4el Steppir boom length is 32′ while the Steppir elements are about 37′ tip-tip<\/p>\n

\"\"<\/p>\n

The driven element Element-to-Boom bracket.<\/p>\n

This is about the time this turned into a YCCC Club project with K1KP Spearheading the efforts!<\/p>\n

Thanks Tony!<\/p>\n

\"\"<\/p>\n

Inventory of aluminum. The Red sections are whats needed.<\/p>\n

\"\"<\/p>\n

How do I get these insulator things off without damaging things??<\/p>\n

POWER TOOLS! Not often permitted for W1UJ….<\/p>\n

\"\"<\/p>\n

The can opener was not utilized…<\/p>\n

\"\"<\/p>\n

Another reason replacing the insulating mounts was a good decision,<\/p>\n

The amount of corrosion under these things was significant.<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

All the aluminum up-to, not including 3\/4″ and lower pieces! Cycle-24 dot com order placed!<\/p>\n

\"\"<\/p>\n

“I dont yet know how to get the thing up there”<\/p>\n

First concept on paper Nixed- (Bad to pull tree over on house…TNX K1KP es K1TTT)<\/p>\n

This is the second concept…Revision A<\/p>\n

\"\"<\/p>\n

What was imagined for the center support.<\/p>\n

Revision A now here, Adds second truss upright to center truss load.<\/p>\n

\"\"<\/p>\n

BoltDepot.com ordered at 10am on Tuesday, arrived 1pm Wednesday. All sorted out.<\/p>\n

When in MA and ordering from here we have to pay sales tax. Cheaper than paying for overnight shipping!<\/p>\n

\"\"<\/p>\n

Cycle-24 dot com ALUMINUM ARRIVED! Unfortunately so hasn’t Hurricane Irene. Hopefully we will be adding to this!<\/p>\n

\"\"<\/p>\n

Drilling Jig arrived! After Ned K1GU said there was difficulty making true holes in the tubing… I found this;<\/p>\n

Amazon dot com, and just under $26, so free shipping too! Had it about 3 days after ordering.<\/p>\n

The rake is the test subject, Mod #1 to the drilling unit = Tied the chuck-key with a lanyard.<\/p>\n

\"\"<\/p>\n

The poor rake….. Works as advertised.<\/p>\n

\"\"<\/p>\n

DXEngineering stuff came in today. Looks rugged, size checked all = OK!<\/p>\n

\"\"<\/p>\n

The Channel Aluminum piece.. Seems very robust!<\/p>\n

(2) 22″ and (2) 2″ pieces<\/p>\n

\"\"<\/p>\n

Dry run lineup.<\/p>\n

\"\"<\/p>\n

Started Drilling and bolting the sections together. They fit on the saw horses now.<\/p>\n

\"\"<\/p>\n

Array of aluminum waiting for elevation and RF!<\/p>\n

\"\"<\/p>\n

It is all fun and games until someone breaks a bit.<\/p>\n

I used a 5\/32″ Bit and the #8 bolt needs to be -almost- threaded in.<\/p>\n

\"\" \"\"<\/p>\n

Elements are complete, only tees and Boom-Elements left<\/p>\n

\"\"<\/p>\n

Aluminum pile is going down<\/p>\n

\"\"<\/p>\n

Getting all of the stuff for the Boom to Element mount together to bring to WA1VVS<\/p>\n

\"\"<\/p>\n

N1WK KE1LI (W1UJ’s Dad, Pete not in photo) Helped take down the 3el Beam on a 35′ TV tower to make way for the new stuff<\/p>\n

\"\" \"\"<\/p>\n

Went to visit Bud_Log Subscriber, Bob WA1VVS to check outcome of first Element-to-boom mount. Freshly carved aluminum on the Bridgeport.<\/p>\n

It is top-notch awesome! Thanks ‘VVS!!<\/p>\n

\"\"<\/p>\n

The position of a ratchet was considered during WA1VVS construction. Top notch!<\/p>\n

\"\"<\/p>\n

All of the aluminum cut for the ‘Tees’. Using a failing tubing cutter, blisters developed on my hands<\/p>\n

until I hit the 1\/2″ tubing and found out how nice a bench vice works to hold the tubing without damage-<\/p>\n

I am getting lots of lessons on this one. K1KP can name those lengths out of memory I bet!<\/p>\n

Temporarily re-purposed the late 1940’s SP-400-x and Early 1950’s R-390(non-a) military receivers in line for restoration
\neventually…..<\/p>\n

\"\"<\/p>\n

The Boom-to-Element brackets are done! Huge thanks to WA1VVS for his skillful expertise in the assembly.<\/p>\n

\"\"<\/p>\n

How many trip hazards can you identify?<\/p>\n

Setting up the new staging area. Make sure everything mounts and transfer it.<\/p>\n

Everyone will be happy to know that the old tower’s Motorcycle Straps are re-purposed here!<\/p>\n

\"\"<\/p>\n

Boom and Truss Mounted. I may re-engineer this this for a bit more balance.<\/p>\n

\"\"<\/p>\n

Close-up of the new Boom-mast plate and truss.<\/p>\n

\"\"<\/p>\n

Dry Run!! Don’t be fooled by the sag, the element halves are just balancing in loose clamps for a size layout<\/p>\n

The boom ‘twists’ about 1\/2″ at every joint with little pressure, so have to disassemble and see whats in the boom<\/p>\n

Budget overruns! Hopefully it is just the existing bolt holes oblong.<\/p>\n

\"\"<\/p>\n

All bolted up an re-trussed the boom completely, thanks N1WK!<\/p>\n

\"\"<\/p>\n

Without element trusses & Reflector Tees, lots of sag. I found the prime spot to attach to the element for trussing.<\/p>\n

\"\"<\/p>\n

N1WK Taping up feedline.<\/p>\n

We raised it out of eye-poking height @11′ and spun it to face SW-ish for tonight’s NA SSB Sprint<\/p>\n

On the MFJ it was 1:0 at 6.8Mc.<\/p>\n

We raised antenna on mast and mast inside tower to get 11′<\/p>\n

\"\"<\/p>\n

N1WK. Aimed South-west.<\/p>\n

1.4:1 @7.200 comparing to ground mounted vertical signals were equal with much less noise on Moxon<\/p>\n

Completed first contest on the Moxon! NA Sprint SSB. 61 QSOs on 40m- 600w with 11 measured feet elevation.<\/p>\n

\"\"<\/p>\n

With this now built, It needs to be modified. Replacing the 1″ and .875″ is necessary.<\/p>\n

The existing .875 looks like aluminum thin-walled conduit.<\/p>\n

The Red sections need to be replaced and adding 18″ inside pieces for strength.<\/p>\n

\"\"<\/p>\n

2 rebuilt\/new sections on the left, 2 bent originals on the right<\/p>\n

\"\"<\/p>\n

Driven element without ends..<\/p>\n

\"\"<\/p>\n

To the untrained eye, this looks like something red in the dirt.<\/p>\n

It is a 5′ screw-in anchor dug out and threaded in with 4 80# bags poured on top<\/p>\n

Tram anchor point near the house.<\/p>\n

\"\"<\/p>\n

Then there was Snow-Tober with a strange Nor’Easter storm during CQWW SSB 2011.<\/p>\n

This storm loaded the elements up with ice and revealed a potential failure spot in the trusses<\/p>\n

\"\"<\/p>\n

The Sch80 PVC Truss wishbones were each filled with oak dowels and adhesive caulking<\/p>\n

\"\"<\/p>\n

“UJ Drop Zone” (Pam coated satellite dish and Pam can be seen on roof<\/p>\n

\"\"<\/p>\n

KE1LI Install day!!<\/p>\n

Could I really have a tower and beam of my own??!!??!?<\/p>\n

The week prior was late nights preparing and work and early Saturday antenna party<\/p>\n

Did I mention ARRL Nov SS CW 2011 is at 5pm tonight??!!??<\/p>\n

\"\"<\/p>\n

Ground crew backs, NR1X, NR1X Harmonic Connor (Jr.), NR1X Brother Mark.<\/p>\n

\"\"<\/p>\n

KE1LI Wrestling the monster on to the mast<\/p>\n

\"\"<\/p>\n

KE1LI Yeee-haw<\/p>\n

\"\"<\/p>\n

Prepping the wires\/feeds and to ‘hike up the mast’<\/p>\n

\"\"<\/p>\n

KE1LI standing on the beacon plate<\/p>\n

\"\"<\/p>\n

KE1LI. An amazing amount of planes flew directly overhead<\/p>\n

I think these are from BOS \/ Logan.<\/p>\n

\"\"<\/p>\n

N1WK KE1LI NR1X Connor Mark Brian Shana<\/p>\n

Without you guys this would never happen. Thank you from the bottom of my heart.<\/p>\n

-tear-<\/p>\n

\"\"<\/p>\n

Take a look at my 40m QSO count in the SS…<\/p>\n

The layers of stations would not stop.<\/p>\n

Ended with 750 QSOs on 40m alone ~1200 total<\/p>\n

I think the highest single band count of any other 3830 log at this time<\/p>\n

\"\"<\/p>\n

“It’s Smiling at me!”<\/p>\n

\"\"<\/p>\n

When waking to go to work Monday morning, This is what I observed….<\/p>\n

\"\"<\/p>\n

Kodak moment for KE1LI….<\/p>\n<\/div>\n
