Our ALUMA T-50H TOWER
I’m in the process of changing out the current tower installation to a mid pivot swivel point that Aluma Tower recommends. I’m ordering a new MP2 post next week and moving the tower to another place in the backyard.
Important!! If you decide to install the tower as I originally did, there is a lot of strain on the 2 bolts that connect the tower leg base to the T Base. Make sure you use large stainless steel bolts with nylon sleeves that fit between the tower holes and the bolts. The bigger the hole, the less tower base leg you will have to withstand the pressure. I thought of using the Hinge supplied with the tower and mounting it on the T-BASE to the Base of the tower. But that’s not what it’s designed for.
Some hams have asked about mounting the pulley cable directly to the house and not to the MP2 post. Don’t ever use a house bracket or pulley connected to the house. The weight will rip the bracket/bolts off the house and cause structural damage. The MP2 post takes a lot of strain when lifting the tower from it’s base. Especially with the weight of a Mosley HF tri-band, 2 and 6 meter yagis. We have had 3 noreasters here on Cape Cod the month of March 2018 and after 5 years, one of the 2 bolts started to bend.
I suggest installing the tower as shown in the lower photo. I plan on mounting the MP2 post 10 feet away from the back of the house. When the tower is lying down, it’s 7 feet from the hinge (pivot point) to the base of the tower. That will leave 3 feet clearance from the tower base to the house.
The T-50H Aluma Tower I own does not require guy wires but there are 3 Guy holes at the top of the tower if needed. Make sure all guy wire parts are stainless steel, including u-bolts, turnbuckles and guy anchors which are galvanized steel. Make sure you use commercial grade 3-4 foot length galvanized guy anchors. I purchased mine from a Cell tower company. Make sure the top hole is enclosed and NOT open as the pressure could bend the steel and will open the hole and the guy cable could fall out under pressure. Local hardware stores sell that type. Don’t buy it.
Sometime in late April I will begin the installation with photos. I’m purchasing a new MP2 post as the old one cannot be removed from 5 feet of cement. Jackhammering will cost up to $1,000 labor.
I hope this information was helpful. The T-50H tower has been in service for 7 years and works as well as it did when I first purchased it in 2011. A great investment for amateur radio operators who hate climbing towers.
Thanks all .. 73,
Newer installation begins in April 2018..

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.
We bought 16 more bags of concrete.
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..
Part 4-Grounding,Guying,Rotor,Antennas and Coax
4 ft. Galvanized screws anchors,shackles and T 304 stainless turnbuckles.
