ANTENNA MAST COUPLER / RETAINER / GUY RING

This is it! Finally, close tolerance HD steel Couplers that join and reinforce 5′ mast sections of 1.9” OD galvanized fence rail (industry size 1-1/2 or 1-7/8?) OR 1.740” OD EMT (industry size 1-1/2”).  You can purchase them in either of two options.  They are not interchangeable.  See ‘Order’ link to purchase.

In its finished form, see figure 1, Option 1 (see below) might be called a ‘No Hang-Up’ Coupler that will quite easily pass through your standoff  brackets. So, all you have to do is drill the 5/16” holes in the 5′ sections of your chosen mast material, assemble with Couplers and raise. Click ‘Prepare/raise’ link for details.

The Coupler is an 8” piece of thick walled DOM steel, yield point around 70,000 psi, that you purchase from this website in your choice of options to fit one of the two mast materials.

NOTE: These options apply equally to both:

  • 1.9” OD FENCE RAIL (Industry size 1-1/2 or 1-7/8?)
  • 1.740” OD EMT masts (Industry size 1-1/2)

PURCHASE OPTIONS FOR COUPLER:
(REMEMBER: You need a coupler for each joint and every 5 feet of unsupported mast)

Option 1: $14.00: Finished Product: Machined (ends beveled, holes drilled and tapped), then zinc spray painted. Stainless pan head bolts are included. (see figure 1)

Figure 2

Option 2: $12.00: Economy version of above without bevels. Will not clear standoff brackets as easily. (see figure 2)

PURCHASE OPTIONS FOR GUY RING RETAINER (GRR):

For your top Guy Ring, you’ll need a Guy Ring Retainer (GRR).  This is a 1” wide (+/-) piece of the same DOM steel as the Coupler.  It’s only needed at the top of the mast as the Couplers act as the Guy Ring Retainers going down at your desired guy rope levels.

Option 1: $4.00: Finished Product: hole drilled and tapped, then zinc spray painted. A stainless pan head bolt is included (see figure 1)

PURCHASING THE GUY RINGS: $5.00 each

Depending on your choice of  mast material options, you will receive the correctly sized guy rings.
