The MFJ-1046 is a compact, lightweight device that can be easily installed in your shack or mobile setup. It is designed to work with a wide range of receivers, including those with balanced or unbalanced inputs. The pre-selector features high-quality, low-loss components to ensure minimal signal loss, and its aluminum housing provides excellent shielding against electromagnetic interference.
The MFJ-1046 is easy to use, with a simple rotary switch and LED indicators for each band. It also features a bypass mode, allowing you to temporarily disable the pre-selector for testing or when not needed. The pre-selector is powered by 12V DC, making it compatible with most radio power supplies.
In summary, the MFJ-1046 Receiver Pre-Selector is a high-quality, versatile, and easy-to-use device that can significantly improve the performance of your radio receiver. It is a must-have tool for any amateur radio operator looking to reduce interference and improve signal quality.
Pros of buying a MFJ-1046 Receiver Pre-selector:1. Wide Bandwidth: The MFJ-1046 offers a wide bandwidth, which allows you to receive signals across a broad range of frequencies. This is particularly useful for amateur radio operators who want to monitor multiple bands simultaneously.
2. Improved Signal Quality: The pre-selector feature of this device helps to reduce noise and interference, resulting in clearer and more stable signals. This can make listening to weak signals much easier.
3. Adjustable Attenuator: The MFJ-1046 has an adjustable attenuator, which allows you to reduce the strength of strong signals that might overload your receiver. This can help prevent distortion and improve signal quality.
4. Compact and Portable: The MFJ-1046 is compact and lightweight, making it easy to transport and set up in different locations.
Cons of buying a MFJ-1046 Receiver Pre-selector:1. Price: The MFJ-1046 is not the cheapest pre-selector on the market. If you're on a tight budget, you might want to consider other options.
2. Manual Tuning: Unlike some pre-selectors, the MFJ-1046 does not have automatic tuning. This means you'll need to manually tune it to the frequency you want to listen to.
3. Limited Frequency Range: While the MFJ-1046 covers a wide range of frequencies, it does not cover the entire HF band. If you're interested in very low frequencies, you might need to look for a different pre-selector.
Conclusion:The MFJ-1046 is a high-quality pre-selector that offers excellent signal quality, wide bandwidth, and adjustable attenuation. It's compact, lightweight, and easy to use. However, it's not the cheapest option on the market, and it doesn't have automatic tuning or cover the entire HF band. If you're looking for a reliable pre-selector that can improve your reception and are willing to pay a bit more for it, the MFJ-1046 is a great choice. But if you're on a tight budget or need a pre-selector with automatic tuning, you might want to consider other options.
Recommendation:If you're looking for a reliable pre-selector that can improve your reception and don't mind manual tuning, the MFJ-1046 is a great choice. Its wide bandwidth, adjustable attenuator, and excellent signal quality make it a valuable addition to any amateur radio station. However, if you're on a tight budget or need a pre-selector with automatic tuning, you might want to consider other options. Do your research and find the pre-selector that best fits your needs and budget.
6 to 33 MHz hf band is covered in five overlapping bands. It vastly improves the most expensive receivers. The entire 8 to 1 tuning range and a vernier reduction drive gives you precision.
Excellent attenuation in adjacent contest bands. Mfj-1046 receiver pre-selector, new passive pre selector has extremely high dynamic range. Fully shielded metal enclosure. An air variable tuning capacitor, 1.
The unable series tuned circuit works into a very low impedance formed by broadband torpid transformers. Protects your sensitive receiver input from damage including switching diodes and attenuate resistors caused by very strong signals multi-transmitter, multi-band operation contests, field day, nearby hams, cabers, TV FM am stations. It eliminates phantom signals by suppressing strong out-of-band that cause inter mod, blocking and cross modulation. Has narrow band width , excellent stop band attenuation, very low loss, constant band width and gain over each band.
Completely eliminates second order inter mod problems caused by strong out-of-band shortwave broadcast signals mixing and producing unwanted in band. It improves the performance of nearly any hf or shortwave receiver transceiver. Especially helpful to those with broadband front-ends that are prone overload. Mfj unique hi-q series unable circuit gives you superb performance.
