  • Indicates the Condition of Any 52 Ohm Antenna and Coax
  • Designed to be Used for Base Operations or Mobile Operations

The Astatic PDC7 Compact SWR Meter is a compact 3-function test meter that tests for SWR, field strength. and RF power. This product is designed to be used for base operations or mobile operations giving it great versatility for its low price point.

This model can be permanently installed and comes with 2 outlets; one from the radio and the other to the antenna. However, its compact size makes it the best SWR meter for carrying on the go, too.

The main unit is powered by two alkaline batteries (not included). It’s designed to operate between 26 & 30 Mhtz and calibrated to work with a resistance of 50 ohms, so it’s built to handle most standard loads. Simple, functional, and powerful!

Setting up this meter is straightforward, though users will quickly notice the dial’s sensitivity. Incorrect adjustments can lead to erratic and inaccurate readings, necessitating a reset of the base station to ensure precision.

A poorly configured SWR meter can result in a sporadic indication of signal strength when a radio transmitter is present, thereby confusing the receiver as to what spectrum conditions are occurring. However, all of this means that the Astatic’s dial can be fine-tuned to exactly the frequency you need with a little bit of careful attention to detail.

The Astatic Compact SWR Meter is an incredibly versatile tool. Even though its manual controls can be tricky, they are just as effective as, if not more than, competing meters.

With the right settings, the meter’s readings will be more uniform, and that’s not even talking about the plethora of other applications it can be used for — ranging from an antenna analyzer, a repeated measurement tool, and even a wave generator.

Driver’s Product SWR Meter for CB Radio Antennas

Driver's Product SWR Meter for CB Radio Antennas Heavy Duty Metal with...
  • EASY TO INSTALL! Compatible with all CB radios that have standard SO-239 connection, handheld models included
  • Works on the CB frequency range of 27 MHz
  • SWR readings ranging from 1:1 to 1:3 and has a 52 ohm impedance rating

The SWR meter is a must for any CB radio operator. It allows you to easily measure the strength of your CB signal and adjust your antenna accordingly.

This Driver’s Product SWR meter has an LED display that shows you the frequency, mode, battery voltage, and RF power output when you press a button on the unit. It’s easy to read at a glance!

It easily switches between AM/FM/SSB/FRS/GMRS/MURS frequencies with one simple push of the button. You can use it on both VHF/UHF bands to check any CB radio or HAM radio.

While this meter efficiently displays your SWR in real-time, its limitation to only measuring SWR overlooks the comprehensive functionality expected from a multi-meter. Without power output testing capabilities, users may lack critical information for optimal antenna adjustments.

It’s good to see that it has heavy-duty construction — even with the small size of this product — but power testing will yield more helpful information for users.

It’s no surprise we recommend the Driver’s Product SWR power meter as one of the best SWR meter pieces for CB radio enthusiasts. Some consumers have been having problems with old-type meters and jamming signals.

Buyers have been thrilled about this new and improved SWR meter that can offer crystal clear accuracies between 1:1 and 5:1 with the user’s choice of measuring frequency. However, since it lacks a little bit of important measurement information, it doesn’t quite measure up to the Daiwa or MJF SWR power meters.

What We Don’t Like
  • Doesn't test power output
  • High price for low functionality

Workman SWR2T SWR Meter for CB Radio Antennas

SWR METER for CB Radio Antennas with 3' Jumper cable - Workman SWR2T &...
  • SWR Test Meter CB Radio Frequency Range 27 MHZ
  • SWR 1:1 to 1:3 / 52 ohm impedance
  • SO-239 Input and Output Connectors W/ Heavy Duty Metal Case

The Workman SWR2T Meter is designed to be used with CB radio antennas, including the SWR2T and CX-3. This SWR meter has a unique dual-frequency internal design.

The meter automatically switches from the first radio frequency (27 MHz) to the second CB radios’ frequency (50 MHz) when you connect an antenna that has the right impedance for each band.

Both frequencies are displayed on a high-visibility LCD display. When you switch back, the CB/SWR/HAM radio meter automatically switches back to 27 MHz.

The included 3-foot coax is one of the best perks of this meter for CB radios, as it makes it easy to use right out of the box. If your CB does not include this feature (which most inexpensive and some expensive versions do), you will likely fry your CB and get crappy reception.

This SWR meter boasts a user-friendly design, though the included instructions fall short of being helpful. Fortunately, ample online tutorials are available, showcasing the simplicity and ease of use of this tool.

As for its size, a SWR meter is a small device that can be easily affixed to the end of the antennas. It’s designed to measure the gain or weakness of an antenna and is also used in amateur radio or radio DX transmissions.

A good SWR meter will offer accurate readings with a soft arc and a well-calibrated knob. We wouldn’t describe the metal frame of our model in that way, but its build quality is what you’d expect at this price point.

Thus, although the Workman SWR2T performs adequately, it does not rank among the top SWR CB/HAM radio meters, primarily due to inadequate user support and concerns about its build quality.
