10.2.2020 update ****SEE Pandemic Shipping / Delivery Information Below**** C90 900 MHz Tuned Short Stubby MotoTrBO Portable Radio Antenna This listing is for one known-brand MotoTrBO antenna that was purchased new and then custom fine-tuned by us to obtain an outstanding high level of performance using lab grade equipment in the 900 MHz band from 896 to 941 MHz. The portable radio shown in the photos is for reference only and is not included. Our C90 antenna fits the MotoTrBO 900 MHz DMR portable radios that have a bottom O-ring weather seal and a special 1/4-36 threaded antenna stud to properly fit the portable antenna jack. The grooves for the optional color ID bands are directly under the top cap and ready for use if needed. This antenna is compatible with the following Motorola 900 MHz radio models that are programmed to work only in the 900 MHz band; XPR7580, XPR7580ePlease see our C85 antenna for use in the combined 800-900 MHz band and our C80 antenna for use only in the 800 MHz band FACT: A BIGGER antenna is usually not better, Just really BIG to poke you! IMPORTANT: Please do not make any purchase until you know for sure what frequencies are being used in your portable radio. The custom retuning of the C90 antenna achieves a minimum signal gain of +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 standard mass produced untuned antenna. Our retuning also allows for a much smaller antenna height without any loss of performance by eliminating all of the unused space inside the antenna covering. This custom tuned antenna will be approximately 2.25 inches tall +-0.125 of an inch as measured from the bottom of the PVC radome to the top cap of the antenna. The final VSWR of 1.5:1 or less will occur across your frequency range choice for a true balanced high performance FM narrowband analog or digital communications range. The bottom of the antenna mounting stud is marked with a single blue color stripe. Our antenna meets all of the following criteria; · Must be a new 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 portable radio · Exhibit an excellent resonance with a very low VSWR of 1.5:1 or less over the whole frequency range. · Use a special 1/4-36 threaded stud to properly fit DMR portable radios 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 is still 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. We do not recommend using a standard remote speaker mic (RSM) along with our custom tuned stubby antenna since the speaker mic coiled cord will physically block most of the stubby antenna performance. Portable radio antennas need plenty of clear space in all horizontal directions to work best. However, if you absolutely must use a RSM with your radio you must tie wrap the RSM coiled cord to go in an immediate downward direction close to where it exits the radio accessory connector to avoid blocking the stubby antenna signal. Please see our other antenna listings for our high performance whip antennas. FYI, a tuned 900 MHz antenna is NOT made to operate in the Vhf, UHF, 700, or 800 MHz bands and will definitely not work properly if at all. So do not purchase a 900 MHz antenna and then complain that it does not work with poor range in the other radios bands. Ask us for help before purchasing if you are not 100% confident. 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: We will not be held liable for performance problems or damage caused by any antenna being used outside of the tuned frequency range or due to the wrong antenna frequency range chosen by the buyer.Our portable antennas are tested and tuned with a special micro-sized RF bridge located at the antenna connection inside the portable radio chassis. The metal chassis of the portable radio is required for the antenna ground reference/ground plane also known as the other half of the portable radio antenna system. If our portable antenna is tested with random external RF cables, RF adapters, external meters, and without the portable radio chassis, your readings will be completely incorrect and show resonance somewhere other than where it was actually tuned for. For VSWR accuracy the antenna needs to be tested/tuned in the same location as where it will normally operate.It is the buyer’s responsibility to verify what specific frequencies or frequency range is needed. A 900 MHz antenna is not made to work in the Vhf, UHF, 700, or 800 MHz bands.FYI: Just because the antenna purchased fits on the portable radio and looks great does not guarantee communications performance. You must verify the tuned frequency range of the antenna purchased matches the actual frequency range used in your portable radio.We are only authorized to sell and ship known-Brand items to the USA, no exceptions. Items will be shipped to the confirmed USA PayPal address only. Any buyer abuse, fraud, tampering, or illegal activity will not be tolerated and eBay will be notified of the situation.The TERMS and CONDITIONS as listed will not be modified in any way after the item is purchased.
