DX Engineering's Dual-Band THUNDERBOLT® 40/30 Meter Vertical Antennas are high performance dual-band pile-up busters that are tunable to operate with an SWR of 1.5:1 or less across both bands. The maximum power rating ensures solid performance, particularly on CW. Plus, the digital modes are popular on 30 meters. 

The massive EXTREN® channel insulator supporting the rugged structural grade type 6063-T832 drawn aluminum antenna radiator has over twice the tensile and flexural strength of competitive nylon plastic materials, and they are superior for their RF handling characteristics. Designed with rugged 6063 heat-treated, corrosion-resistant aluminum tubing and stainless steel hardware, these antennas are very durable and attractive. 

Now, you can have full quarter wave performance on both bands without having to compromise. Of course, another key to performance is a good ground radial system. We recommend 32 radials, 32 ft. long. Fewer radials will work, but with diminished results. These antennas include the antenna element, insulated Extren mounting channel, mounting plate, tilt base, stainless steel hardware, and stainless steel element clamps. See Suggested Parts for additional items that will enhance the performance of your installation.

DX Engineering's Dual-Band THUNDERBOLT® 40/30 Meter Vertical Antennas feature:

* Full band coverage on 40 and 30 meters with SWR under 1.5:1, with no tuner needed 
* 40m bandwidth greater than 750 kHz with SWR under 2:1 
* Tunable above and below 7 MHz range for MARS and CAP frequencies 
* Over maximum legal power handling 
* Optimum 30 ft. overall height 
* Self-supporting design to withstand 60 mph wind without guying
