M36 Stubby Antenna for Motorola XTS Public Safety Mic RMN5073B XTS2500 XTS5000

Description: 9.20.23 update M36 Tuned Short Stubby Antenna For Motorola Public Safety Microphones (PSM) used in the UHF, 700, 800, or 900 MHz Radio Bands For Optimum Radio Communications Range Our antennas are purchased new from a known-brand company, then disassembled and custom fine-tuned by us to obtain an outstanding high performance level using lab grade network analyzer equipment to one of the 13 different variation frequency ranges listed that you must choose from. Our tuned antennas are unlike any other portable antennas being sold. Stop getting poked in the eye or face with the tall factory OEM antennas by purchasing our short tuned antenna. Our M36 antenna looks professional and will have extended radio communications range. Our tuned antennas are specifically made and optimized to be used on top of the Public Safety Speaker Microphone (PSM) that should be attached to the shirt epaulet for maximum communications range under all conditions. This M36 antenna is compatible with the following specific Motorola PSM model’s; NMN6228 NMN6234 NMN6243 NMN6244 NMN6247 NMN6250 NMN6251 RMN5072 (see UHF NOTE below) RMN5073 (see UHF NOTE below) RMN5074 (see UHF NOTE below) RMN5075 (see UHF NOTE below) RMN5076 The PSM part number can be found labeled on the back side of the mic housing. Any letter listed on the end of/or after the part number like A, B, C, or D is just a mfg revision level that will not affect the antenna needed. UHF NOTE: The public safety speaker mics with model numbers ending in 5072, 5073, 5074, and 5075 are designed by Motorola for use ONLY in the UHF band 450-512 MHz. For use on Vhf and any other UHF frequency the PSM internal circuitry will need to be modified to remove the engineered frequency limitations. The Motorola PSM’s listed above work with the following Motorola portable radios; ASTRO, JEDI, HT1000, HT750, HT1250, HT1550, JT1000, MT1500, MT2000, MTS2000, MTX-LS, PR1500, VISAR, XTS1500, XTS2500, XTS3000, XTS3500, and XTS5000 portables. Yes, it is a known fact that the known-brand PSM straight connecting cord design uses a small diameter internal RF coax cable which introduces a signal reduction to all TX and RX signals between the PSM and the portable radio. With our tuned M36 antenna you can cancel all of the negative effects from the small coax cable and really improve your communications performance as compared to any other competitive antenna available. Your antenna will have a final VSWR of 1.5:1 or less across the advertised frequency range variation choice for TRUE high performance FM narrowband analog or P25 DIGITAL radio communications range. If you need a frequency range that is different from what is listed please let us know so that we can design a solution for you. If you need a wider frequency bandwidth antenna please see our other antenna listings. Our photo illustrates what our antenna will look like on top of your Public Safety Speaker Mic. This listing is for the purchase of the antenna ONLY and does not include a public safety speaker microphone that is shown for reference only. ---------------------------------------------------------------------------------------------------------- M36 Antenna Ordering Instructions: Please choose the frequency range that you need from the following list of different antenna variations available.

What more can we say about our tuned antennas? Why continue to operate with an unproven portable radio antenna on top of your PSM, When you can STEP UP to the TRUE level of Public Safety Mic Antenna Performance! Unleash the full potential of your portable radio with our Custom tuned antenna! For a very high Performance & Quality antenna Why wait? Just use the “Buy It Now” feature! MORE DETAILS All of the PSM models listed above use a dummy/fake Look-A-Like SMA male jack with the center pin wired to the jack outer threaded section. This can be verified when the PSM is disconnected from the portable radio by checking the continuity between the center pin and the outer jack threads using an OHM meter. Transmit RF output cannot be metered or measured at this fake jack. Our special M36 PSM antenna with a threaded stud and center hole is designed to have maximum communications performance with this fake SMA jack. Our testing is performed on a public safety speaker microphone located on the user’s shoulder/shirt epaulet. Every antenna is tested and must pass all specs to be released for sale. · Our tuned UHF antennas will vary in height between 1.9 inches and 2.4 inches tall depending on the frequency range. · Our tuned 700/800 antennas will vary in height between 2.4 inches and 2.8 inches tall depending on the frequency range. · Our tuned 800 only antennas will vary in height between 2.0 inches and 2.3 inches tall depending on the frequency range. · Our tuned 900 only antennas will vary in height between 2.2 inches and 2.5 inches tall depending on the frequency range. All antenna length measurements are made from the bottom of the weather skirt to the top cap of the antenna. The lower frequency ranges will always have the longer antenna lengths. The lower frequency antennas will have the longer antenna heights. The higher tuned frequency antenna will have the shorter antenna heights. The antenna covering is made of black flexible PVC and has a bottom skirt to weather protect the RF connection on the radio housing. The bottom of the female SMA Motorola type connector is color coded with a stripe which identifies the tuned frequency range. We silver solder all reworked internal antenna connections for the best RF signal transfer. The retuning of the known-brand helical antenna achieves a minimum signal gain of up to +3 dB that will effectively double your transmit and receive signal power due to the very low VSWR and excellent 50 ohm impedance match as compared to any untuned antenna. Our custom retuning also allows for a much smaller antenna height without any loss of performance by eliminating all of the unused/wasted space inside the OEM antenna covering. Please see the Certified Performance VSWR graph images. Our antenna meets all of the following technical criteria; · Must be a known-brand antenna and not a cheap junk or aftermarket 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 Public Safety Microphone. · Exhibit an excellent resonance with a very low VSWR of 1.5:1 or less over the whole frequency range. · Uses a special threaded stud connector with a center hole to properly fit the public safety speaker microphones for all of the specific models listed above. · Must maintain all specifications over the temperature range of -10 to +120 degrees Fahrenheit. 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 into RF power on receive. 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 OEM antennas get beat out performance wise by users with radios one forth the cost using our fine tuned antennas. 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. 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 efficient transfer of RF power. Any VSWR above 1.6:1 is poor and any VSWR above 2:1 is definitely BAD for the performance and the long term health of the radio RF power output amplifier. 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. FYI, a tuned antenna is designed to operate only in the advertised frequency range. A tuned UHF antenna will not operate in the Vhf, 700, 800, or 900 bands. A tuned 800 only band antenna will not operate in the Vhf, UHF, 700, or 900 bands. A tuned 700-800 band antenna will not operate in the Vhf, UHF, or 900 bands. A tuned 900 band antenna will not operate in the Vhf, UHF, 700, or 800 bands. Any antenna forced to operate outside of the tuned frequency range will definitely not work properly if at all, and will eventually cause expensive internal damage to the portable radio power output amplifier. So do not purchase our tuned antennas and then complain that it does not work with extremely poor range outside of the designed frequency range. Just because the antenna fits and looks good does not mean it will work properly. We have built tens of thousands 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. ---------------------------------------------------------------------------------------------------------- TERMS and CONDITIONS: Our TERMS and CONDITIONS as listed below will not be modified in any way after the item is purchased.Items will be shipped to the confirmed USA eBay address only.Any buyer abuse, fraud, tampering, or illegal activity will not be tolerated and eBay will be notified of the situation.Please be aware if these terms and conditions are not met, eBay will be notified of Non-Performing Bidder, appropriate bidder feedback will be given, and the item will then be relisted for auction again.All photos, images, and text used in the auction are all the IP (intellectual property) of rcbi.Antennas: We will not be held responsible for performance problems caused by any antenna being used outside of their advertised tuned frequency range or due to the wrong antenna frequency range chosen by the buyer.
