Our ALUMA T-50H TOWER

November 1, 2016

    Thanks for visiting! N2KNL amateur radio website started October 2016. The N2KNL amateur radio pages were part of the RadioTimeline.com site since 1999. Thousands of hams worldwide have visited the old and new site.

My wife, Elaine KB1VAJ and I purchased our Aluma T-50H Tower June 2011 and it’s been in service 6 years. It’s been some time since there has been an update on the tower page. Many of you know, Aluma Tower Company manufactures an excellent product! The T-50H has been through all kinds of weather here on Cape Cod. High winds (numerous wind gusts up to 73 MPH), extreme temperatures, moisture, rain, snow, sleet and sun. We added equipment to the tower, a Davis Vantage Pro2 6152 cabled weather station and 3 wired cameras with a great 65 foot high view. I’m almost 60 years old and lowering/tilting over the tower for maintenance is essential. My climbing days are over! lol 🙂

The ALUMA  TOWER T-50H INSTALLATION


Part 1- PERMIT / DELIVERY

The Town approved the tower permit June 17, 2011. The fee was $50 and the Building Inspector was very knowledgable on tower installations, from amateur radio to cell towers. The process from application to approval was 6 working days. A day later I picked up the permit and ordered the tower.

The tower and accessories shipped in a 26 foot wood crate. The shipment departed Monday August 8th from the Aluma Tower Company in Vero Beach, Florida via YRC Yellow Freight. Delivery was Friday August 12th. Russ K1RTA offered his help and the use of a cement mixer. Thanks so much! …The tower arrives!

The Crate size was 26′ x 2′ x 2′ and weighed 796 pounds! Russ K1RTA pulled the crate with his vehicle and dragged it onto the driveway. The crate size seemed intimidating but it was easy.

Russ, Joe and I dismantled the crate. It was easy with 1/2 inch pine and thin staples. Most of the weight was the MP-2 Ground Post. The tower was only 100 pounds! My wife, KB1VAJ took the photos.

Unloading time was 2 hours. Aluma Tower did a great job crating the tower to ship. The company sells a great product and it is well worth the money.


Part 2- The Foundation

 A few days after delivery, Russ and I began work. The foundation size was 44″w x 34″d x 36″h. That’s rather large for a T-50H tower (standard size is 30″ x 30″ x 36″). We made the foundation larger due to more sand around the house which was easier to shovel than dirt and rocks. 2 hours and 20 wheelbarrows later we cut part of the wood crate into 36″ x 10″ boards to form the foundation. The wood is held together with screws.

42 bags of Quikcrete was delivered yesterday, August 9th. Assembling the rebar cage and mounting the foundation screws to the T-Base today. Tomorrow we mount the MP-2 post and rebar cage and then pour.

Part 2-Tower Installation

  Before connecting the tower to the T-Base, I installed a 3,000 pound 12 Volt DC Full Breaking ATV Winch from Harbor Freight., a NAPA Deep Cycle Marine Battery / Battery Box and a Battery Minder Charger/Conditioner. These items will replace the manual winch that came with the tower. It takes too long to hand crank. A high torque cordless drill was sufficient.

   A PERSONAL NOTE;  The MP2 Mounting Post was installed another way with the tower base anchored to the T-Base and pulled upward by a pulley mounted at the top of the MP2 (see above photos). Most installations use the method seen below..
