2005 Summer Tower Work

Quick Index

The big work for this summer is the installation of an M-Square 40M4LLDD.† This is a 4 element linear loaded design with dual driven elements.† It has a 42’ boom and the longest element is 50’ tip to tip.† It weighs in at about 150#.† See my tech note on balancing big antennas for some pictures of it on the ground under construction.



This is the rigging getting ready to lift.† Note that I used a large rope tied to 2 places about 6’ apart on the boom to spread the lifting force a bit.† This also keeps the rope clear of the boom-mast plate which makes putting U-bolts in a bit easier.† The ropes are attached to the boom in a way that will force the elements to tilt upward toward the tower when the antenna is lifted to make it easier to get over guy wires.†

The view toward the tower shows the two tag lines, notice that they are tied with large bowline knots so that the knot can be untied and the rope removed from the boom while up the tower easily.† What can’t be seen from this is that the antenna is backwards.† The reflector is on the left in the picture, but when it is up on the tower the reflector has to be to the right.† This is because I want to put the antenna on the far leg of the tower pointing the opposite direction toward Europe. You also can’t really see that the tram cable goes up to the guy bracket at 140’, but the antenna is destined for just above the 105’ guy bracket.

There weren’t enough people when we did the liftoff to get some pictures.† Basically I first untied the temporary rope that was keeping the lifting line from pulling the antenna off the tripods while someone held it back.† Then I increased tension on the tram line which actually lifted the antenna off the tripods so we could check the balance before sending it up.† The balance was good so the Jeep in 4wd-low backed up from the tower to pull it up.†

Once it was above the 105’ guy bracket the tram wire was loosened so the antenna swung in toward the tower and came to rest on the guy wires just below the bracket.†

Here is the tag line crew hard at work.

Once I was up the tower the Jeep pulled the antenna up to its final height.

Once it was above the 105’ guy bracket the tram wire was loosened so the antenna swung in toward the tower and final height.†

I then swung the antenna around the tower.†

Now its pointing the right direction and the boom-mast plate is on the right leg of the tower so I put in the U-bolts.†

After the U-bolts were in it was time to remove the tram line and tag lines.

Then it is time to install the boom brace.†

I connected the coax and came down to release the supervisor

A regional meeting/picnic for the Yankee Clipper Contest Club was held onAugust 27, 2005 at the station of Dave Robbins, K1TTT in Peru, Massachusetts. The picnic started a little before the scheduled noon start. A brief business meeting began at approximately 1:00 p.m. to vote on several new member applications. 

Tom Wagner, N1MM, was on hand to demonstrate the N1MM Contest Logger. Dave continues as an active member of the N1MM Contest Logger Software development team. His multi-multi station uses this software for all major contests. Tom gave an overview of the software operation and then demonstrated it operation in the Ohio QSO Party. Several of the group gave the software a test drive.

Tours of towers and antennas were conducted.  These included discussions of construction techniques, grounding, stack design and switching.  There were also demos of tower tools, how to install deadends, and other tower stuff.

Daveís new deck is a great place to hold a cookout and view the extensive antenna farm. There were plenty of burgers and hot dogs from the grill and lots of other good food.

Our goal to attract new members was very successful. Six completed applications for membership were received and all voted into membership. The new members are: W2RU, Bud Hippisley;  KA2WIN, Linda Hippisley; W3UA (RA3AA), Gene Shablygin; W1BNC, Mike Keller; N1MGO, Gordon LaPoint; and RX9UL (KC2OOV), Oxana Sinyakova. Completed application and dues will be forwarded to the secretary and treasurer.

This was the largest crowd ever to visit the recently established Berkshire Insulator Gallery.

We were pleased to have YCCC Vice President, Brian Lambert, N1IK in attendance. There were twenty-nine YCCC members attending, including our new members.
