We are restructuring!

We are pleased to inform you that we have merged with another local supplier, Push To Talk South Africa (Pty) Ltd [PTT SA].

We negotiated this restructuring venture in order to add additional support and two way radio communication equipment to our existing product portfolio available to all DRS customers.

We came across an old blog post by Michael Martens, which contains an excellent explanation of what it means when people talk about Antenna Gain / Dbi.

Since it also clarifies the reason for antennas in the two way radio world, we HAD TO share.

“I’m gonna take a confusing subject and hopefully demystify it. Antenna Gain is a popular subject amongst hams. We talk about gain all the time, we’ll compare antenna systems and apply values to as how impressive they are by their gain figures. But what exactly is antenna gain, and what do those numbers mean to…”

In 1993, Bob Allphin and a team of 11 other men took a boat to remote Howland Island, an uninhabited slip of coral that is officially part of a group called United States Minor Outlying Islands located in the Pacific Ocean.
It’s not a place where tourists tend to gather, save a very specific breed. “If that rings a bell,” says Allphin, “It’s because that’s the island Amelia Earhart was looking for when she ran out of gas and disappeared.”
The trip was going according to plan, but as the week progressed, the waves offshore grew larger and larger.

Powerless, the small gathering could only watch as the whitecapped water separated them from their main vessel. With ample supplies visible off shore, they ran out of water.
“And there’s no worse feeling because you’re on an island where the temperature is 120 and you’re thirsty as hell,” says Allphin.
The dozen tourists combed the beach for upturned seashells filled with rainwater and strained that through a t-shirt into a bucket, adding iodine pills. This was the stew they planned to subsist on when they had a breakthrough—the crew was able to get water ashore. Still, they wound up stranded on the island an extra seven days.

Perhaps the most shocking thing is that this group risked their lives for a passion that is esoteric even by esoteric tourism standards—they weren’t out at the remote island for Amelia Earhart. They were there to make contact with as many amateur radio operators from all over the world as possible.

According to the American Radio Relay League, which is the national membership association for amateur radio operators in the U.S., there are around 3 million operators worldwide.
