Kenwood D75 antenna options?

[KM6KOZ]

The stock antenna seems to work better than most "rubber ducks," so I am impressed.

I bought a SRH320A and a SRF10... the 3" antenna appears to work better than the 320A! Anyone know of a spectacular antenna + D75 radio combinations?

While I would like a triband antenna, there aren't many around and I don't use 220 anyway.

The handheld antenna market is flooded with antennas at various lengths for 2m/70cm. I've tried a few of the more popular ones and compared them to OEM antennas on the Kenwood TH-D74 and Yaesu FT5D. I found no appreciable difference among these antennas.

I went through the same process of trying a few antenna's for the D75. As usual everyone has a favorite, nothing works and everything works. RF is a funny thing but I tried the Signal Stuff antenna and in my environment it has performed exceptionally well at home and mobile. If I got another handheld I would buy another Signal Stuff. I don't like how long it it is but I do like you can twist it in a knot. Very durable - nothing is perfect.

Your mileage may vary

I have legitimate versions of the Diamond SRHF10 and the SRH320A. The Diamond SRH320A is superior. I have used and tested both on Kenwood TH-F6A, D72 and D74 handhelds, as well as others. The performance of the 320A motivated me to purchase more and use them with other handheld transceivers as well as scanners and receivers.

The best performing antenna mounted directly to a hand held is a single band telescoping.

The best dual band “rubber duck” I have tested is the Motorola PMAT4001A. The connector on that is SMA female though. Thus, it works great on Moto APX, XTS, as well as various Chinese handhelds, but not on the Kenwood.

Diamond also makes some crazy long dual band handheld antenna that is two pieces put together. I have not tested that.

I've been playing around with BNC antennas using SMA-to-BNC adapters, and they've been a great way to standardize my setup across various HTs. Some of my rigs have the Chinese-style ("innie") SMA connectors, while others use the Japanese-style ("outie"), so the corresponding BNC adapters let me mix and match antennas easily, and make it a breeze to hook up to a mobile whip or mag-mount when I'm operating from the car.

Along the way, I picked up a couple of the cheap HYS-701N BNC antennas off Amazon, and to my surprise, they actually perform quite well. I don’t have any hard data, but running the D75 on EL power into my hotspot while walking the neighborhood, the signal seems noticeably more stable compared to the stock rubber duck that came with my Kenwood.

SMA-to-BNC adapters

Have you found an adapter that works well with your TH-D75?

I use the Diamond BNCJ-SMAP adapter on my D75, and other Kenwood dual-band HTs. This adapter almost makes the radio look like it came with a BNC connector, instead of an SMA connector.

I use no-name Amazon ones. The Diamond ones look good, although I've had no problems with the generic adapters. I've used them on my Yaesu, Icom, and now Kenwood handhelds. It's important to get an adapter with a skirt like these to help with strain relief.
