Description: 6.2.21 updated ****SEE Pandemic Shipping / Delivery Information Below**** MW4 UHF Quarter Wave Whip Antenna for Motorola Portable Radios that use a 1/4-32 threaded stud connection in 8 different frequency variation choices across the UHF 420 to 521 MHz Frequency Range This auction is for one high quality well-known brand UHF Whip antenna that was purchased new and then custom fine-tuned and impedance matched by hand with lab grade RF test equipment to cover one of 8 different frequency variation choices in the UHF 420-521 MHz frequency range with less than a 1.5:1 or better VSWR under all operating conditions. Our new MW4 model antenna with 2.15 dBi gain is a higher performance replacement for our previous popular 83A model whip antenna. Today’s radio communications requires a balanced performance for transmit and receive signals. Our antenna uses a special top loading element to create a perfect 50 ohm impedance match and reduce the VSWR even lower across the advertised tuned frequency ranges. No other look-a-like antenna can compare with our high precision standards and measured results. This custom tuned UHF whip antenna is intended to work great with the radio operated on the hip up against the body using a belt clip, duty belt carry holster, or operated in the hand with or without a remote speaker microphone. Our antenna is compatible with the following Motorola radio models; BC130, BPR40, CP100, CP125, CP150, CP185, CP200, CP200D, CP200XLS, CP50, CT150, CT250, CT450, CT450LS, EX500, EX600, EX600XLS, EXPO, GP68, GP300, GP350, HT10, HT50, HT90, HT440, HT600, HT750, HT1250, HT1250LS, HT1550, HT1550LS, MT1000, MX300, P10, P50, P100, P110, P200, P1225, PR400, PR860, PRO1150, PRO2150, PRO3150, PRO5150, PRO7150, PRO9150, SABER, SP10, SP11, SP21, SP50, SP50+, SPORT, and the TS11. This antenna DOES NOT include GPS capability. Note: Our antenna will also work on the multi-band APX portables ONLY if the portables are programmed to operate in the specific tuned frequency range of the antenna. Operation on any frequency outside of the tuned frequency range of the antenna will have poor to no communications range and may cause damage to a multi-band portable. Any other items shown in the photos besides the antenna are shown for reference only and are not included.

Our custom tuned UHF portable antennas up for sale are brand new inventory and meet all of the following requirements; Must be a new well-known quality brand antenna and not a cheap junk look-a-like copy from China.Be as short as physically possible for a low profile with great communications range.Must be professional looking on the portable radio or on a public safety service microphone.Use a 1/4-32 threaded male stud connection to properly fit Motorola brand portable radios.Exhibit an excellent resonance with a very low VSWR of 1.5:1 or less over the advertised UHF frequency variation choice.Must maintain all specifications over the temperature range of -10 to +120 degrees Fahrenheit.Have maximum communications range when used with a remote speaker microphone or with other external audio accessories. Our antennas actually outperform the mass produced competitors 6 to 6-3/4 inch long 450 MHz UHF antennas since each of our antennas are custom retuned by hand for optimum performance over a very specific frequency range with greater precision and accuracy. VSWR is the efficiency measurement ratio of RF power that is being converted into radio waves by the antenna system as compared to the RF power that is not converted and reflected back into the radio as wasted energy. Lower antenna VSWR values will permit maximum transmitter signal output and better received signals. A VSWR of 1.5:1 has been and still is the customary maximum upper limit used in professional land mobile radio communications to determine a good transfer of RF power. Any VSWR above 1.6:1 is poor and any VSWR above 2:1 is definitely bad for performance and the health of the radio RF power output amplifier. We achieve a minimum gain of up to +3dB as compared to a stock OEM untuned antenna since our antennas have a much lower VSWR value and more useable transmitter output power. A gain of +3dB will effectively double your transmit and receive power. All reworked internal connections are silver soldered for best RF conductivity. The outer antenna covering is made of black flexible PVC and the antenna has a bottom weather skirt to protect the SMA RF connection on the radio. The bottom of the antenna is color coded for each frequency range variation. Our custom tuned UHF antennas have greatly improved communications for all business, consumer, commercial, fire, GMRS 462-467 MHz, government, industrial, public safety, police, and rescue radio users who operate in the shared UHF 406 to 521 MHz radio band. Eleven US cities and their surrounding areas within a 50 mile radius are allowed by the FCC to use the UHF 470-512 MHz frequency range also known as the T-Band for land mobile radio communications. The following areas in the US are using the frequency ranges as listed in addition to the 450 to 470 MHz band; Boston, MA 470-479 MHz and 482-488 MHz Chicago, IL 470-482 MHz Dallas, TX 482-488 MHz Houston, TX 488-494 MHz Los Angeles, CA 470-488 MHz and 506-512 MHz Miami, FL 470-476 MHz New York, NY 470-488 MHz Philadelphia, PA 500-512 MHz Pittsburgh, PA 470-476 MHz and 494-500 MHz San Francisco, CA 482-494 MHz Washington, DC 488-512 MHz It is a fact that the most important part of any radio communications is the antenna system. The antenna is the device on a radio that converts RF power into radio waves during transmit and radio waves back into RF power to receive signals. ALL transmitted and received signals must pass through the antenna system for any radio to work. A respected radio engineer once said, “If you had 100 dollars, invest 99 dollars in the antenna system and 1 dollar in the radio and you will always have great communications”. After many years of our own experience we have found that this statement to be true especially for today’s FM narrowband radio communications. We have witnessed portable radios worth thousands of dollars using cheap unknown quality OEM antennas get beat out performance wise by users with radios one fourth the cost using our fine-tuned antennas. Sadly many companies that manufacture products in China now use a VSWR of 2:1 as their good reference point to market their poor quality products and make them appear to be way better than what they actually are. We have built thousands of custom tuned antennas for our customers with excellent results and zero defects. Our company has over 30 years of experience in creating high performance and cost effective antenna solutions. Why continue to operate with an unknown portable radio antenna performance when you can STEP IT UP to the TRUE level of portable antenna performance!
