Improving the Hustler 4BTV antenna

 My Hustler 4BTV antenna has been working great for me and I have no complaints about it at all. With being close to the ocean we often get windy days. The wind gusts can reach 80km per hour and during that time I would take the 4 BTV down and store it in the shed. A company called DX Engineering sells some custom-made add-on kits for the Hustler vertical antennas. DX Engineering offers a reinforced lower section for the antenna. I have noticed even during 60 km winds the antenna sure does sway a lot. I bit the bullet and ordered the heavy-duty lower section. It was shipped the next day and the order status was sent from start to finish. To replace the lower section is very straight forward and the only step that needs to be done is a measurement from the 10m trap section down to where the lower section starts. If you match this distance up then there should be no need to return the antenna. 

The measure distance was 2 inches and I marked it with a sharpie pen. I then loosened the screw clamp and removed the lower section. I then cleaned the 10m trap tubing and reapplied some anti-seize, I then move the new lower section up to the mark and secured the screw clamp. Once the antenna was placed back on the lower base section it was time to check out the SWR. It was a pleasure to see the antenna's SWR characteristics had not changed.

We have had some windy days since then and the new lower section sure has made a difference with stability of the antenna. I am very pleased with the purchase. Unless we have winds over 80Km will I take the antenna down.

Old lower section removed

Anti-seize applied

All back together and ready to go.
