The gamma match of my antenna is a piece of large gauge copper wire, soldered to the copper pipe of the antenna body on one side and secured to a plastic bracket on the other. I needed it to move out just a fraction more than it wanted to optimize the impedance match between it and the transceiver. To keep things in place a quick search around the house brought forth two plastic clothes-pegs a little different to the one pictured to the left.
Initially I wondered what affect the metal clips inside the peg might have but it seems they make no measurable difference.
Bottom line is: Don't be afraid to experiment and challenge the notion that "store bought" is better. You might be pleasantly surprised by what you can create and how well it performs.
