Kenwood TH-D74A Antenna Bushing

Using the TH-D72A antenna spacer as a concept this bushing was created in Fusion360 for the Kenwood TH-74A with a Diamond SRH320A tri-band antenna. The bushing fills the empty space around the Diamond antenna and likely provides a level of strain relief for the radio's SMA antenna connector.

The TH-D74A has a slightly smaller diameter area around the antenna connector, thus requiring a different bushing size relative to older Kenwood handhelds.
