Tower Installation Update

Today (9/13) we poured concrete. Four yards (16,000 lbs.) of mud, 200 pounds of re-bar, followed by

by eight ¾” threaded rods. Everything went as planned. As we wait for the concrete to harden, we can now come up with a plan to relocate the log periodic antenna that is currently atop the Glen Martin tower that is mounted on the shipping containers.

Tower Tilt Mechanism Installed

Today (9/20) the crew of Dave, KR4U; Donn, N4KII; and John KI4UIP installed the tower tilt assembly on the concrete base. Notice the ancient Egyptian influence used in keeping the heavy mechanism above the threaded rod so as not to bend the rods. Now we get to prepare the tower while the concrete base continues to cure.

Tower Installed

Our trusty tower team consisting of John, KI4UIP; Donn, N4KII and Dave KR4U were at it again. Today (9/27) the tower tilt mechanism was mated with the telescoping tower. The tower mounts to the base with two large bolts that also serve as hinges when the tower goes from horizontal to vertical or vice versa. Once the third leg is bolted to the base, the tower can then be extended to a raised height of approximately 54 feet.

Final installation details include adding tower grounding, installing the rotor, mast, and Click for more

It’s Party Time

Yes, it’s time for an antenna get together.

Tower site B
Current antenna location

The plan is to remove the log periodic antenna from atop the storage containers, followed by the mast, rotator and thrust bearing. If you would like to help (or supervise) in this effort, the party starts at 10:00AM on Saturday (9/8) the day after the next SPARC meeting.

Hope to see you there.


Log Periodic Antenna Moved

The Log Periodic antenna was transferred from its old location atop the shipping containers to the new tower by John, KI4UIP; Donn, N4KII; Dave, KR4U; Bob, N2ESP; and Hal, W1EES. Ron, KP2N replaced the logging computer power supply. With luck, W4TA will be ready for the sweepstakes. Click on title for photos.

W4TA back in Contest Mode…New Antennas Work Great

With the completion of the relocation of our Log Periodic antenna on our new tower and the erection of a temporary dipole for 40M/80M, W4TA is on the air. The tower puts the antennas up around 55 feet. And boy do they work well in combination with the Alpha 9500 amplifier. We inaugurated the antenna/amplifier combination in the CW Sweepstakes contest, the oldest contest in amateur radio. It was no effort to hold a frequency and it was fun to hear the pile ups focused on us.

Congratulations to all Click for more
