Active receive antenna vertical configuration, single vertical antenna, two vertical array package for use with ncc-2, four/eight vertical array package (21 pages)
The minimum SWR will vary from as low as 1.2:1 to over 1.6:1, depending upon several variables. The DXE-AOKC-12M 12 Meter Add-On Kit is rated at 1,500 watts PEP SSB, 1,000 watts CW and is conservatively rated for RF power handling of 375 watts RTTY and Digital modes including FT8, at antenna SWR of 2:1 and below.

Ruggedized BTV Reinforced Lower Tube DXE-RLT Build or refurbish any Hustler BTV antenna to be stronger with a DX Engineering Ruggedized BTV Reinforced Lower Tube. The DXE-RLT double-wall aluminum tube is stronger than the original single-wall tube, and it works on all BTV Series antennas, new and old.

Lube SS-30 must be used to prevent thread galling on stainless steel and ensure ideal RF coupling between parts. When mounting the assembled DXE-AOKC-12M to the antenna, You can either tilt the antenna down or remove the antenna from the existing base and use a table to lay the antenna on. Installation of the parts is straight forward and easy to accomplish.

3. Install the wing nut (19), split washer (2), large flat washer (18) and carriage bolt (13) to the tuning rod bracket (15) as shown. Just snug the hardware in place so it won’t come loose, 4. Attach two element clamps (6) to the lower bracket (4) using an external tooth washer (5), flat washer (3), split washer (2) and hex nut (1) as shown.

Tuning Installation of the DXE-AOKC-12M can have the effect of narrowing the SWR bandwidth of 20, 15 and 10 meters, a reasonable trade-off for adding the extra band. After the DXE-AOKC-12M is installed and tuned, any required shift of the usable SWR frequency ranges on those bands is accomplished by trap sleeve repositioning on the respective band trap.
Page 15
If retuning is required make minor adjustments as necessary. Refer to the DX Engineering BTV Installation and Assembly Guide available from DX Engineering. In some installations, particularly those with very good soil conditions or a very good radial system, the traps themselves may have been changed from factory dimensions during the initial installation of the vertical to resonate the vertical in each band.
