Ht1000 antenna

[wbw]

The Mototrbo XPR series antenna will screw into the antenna port of a Jedi or XTS series radios, but it will not work because the ports and the connectors between the two model radios are totally designed differently. In otherwords, it will not even come close to work.

Attached a XPR6000 series connector photo comparison to an XTS. The XPR6000 series antennas work fine with my XTS radios. Many, many, others have confirmed the OEM XPR6000 series antennas work with XTS, APX, HT1000, etc. Note the elastomer o-ring type feature in the XPR6000 photo. I suspect it was added to prevent water egress into the radio connector housing. The XTS looks to be a metal to metal seat with the antenna to radio. The threads are the same and the seating depth is equivalent when you account for some o-ring compression.

I cannot confirm since I don't have any, but have read in several posts the XPR7000 series use a different connector and are NOT compatible.

MotoTRBO Antenna on XTS

Hey y'all, im using a a PMAD4068C VHF+GPS antenna on my XTS5000. Its works just fine but is it possible since it also has GPS in the antenna to use the GPS on the XTS5000? Or more importantly will it damage the PA on my radio? Thanks!

My 403-527 MHz XPR7550e antenna on a XTS5000 radios. I am unable to hit the repeater sitting on a Peak at the 4,000 foot level a few miles away and I have an unobstructed view of the repeater. The radio will not transmit as designed with a XPR7550e antenna. With the appropriate XTS5000 antenna as pictured above, I can sit inside my resident on the opposite of the house in relation to the location of the repeater and have full quieting communications with the repeater.

As you can see, the antenna is screwed in all the way and will not property seat and is not the appropriate SMA connector for this radio with no means to properly connect independently with the center pin.

The antenna on the left is a MOTOTRBO XPR antenna and the right Antenna is for the Jedi, Astro Saber, Visar, and XTS series model radios.

Sorry, only half true. The antenna in your photo on the left is for the Gen 2 XPR radios like the 7550/3500, etc. But the antenna in your photo on the right will fit the XPR6550, 6350, Jedi, Astro Saber, XTS3000/5000, & APX.

The XTS5000 antenna will not fit and seat on my XPR7550e radio.

Not really those are designed for xpr-6550 not jedi series. There a reason the OEM designed a particular antenna for a specific radio regardless of whether they use same connector.

Many people seem to think that the newer antenna designs seem to perform better than the older legacy antennas. This would depend upon the specific antennas you are comparing. If your statement is 100% true, then why are there so many aftermarket antennas sold?

The SMA is not an OEM motorola never seen an OEM with a dark green band and gasket on the base

Excuse me.

And here is the Motorola Stubby version.

you got some knock offs

Are you saying that Motorola sold me some knock offs? Those dirty idiots. I need to write a letter and do some complaining and threaten to take my Motorola business to that warehouse company operation with all that cheap counterfeit Pandaland stuff.

Most of us know that a portable radio antenna operates on a poor platform to begin with. Just for giggles, I decided to see what would be the performance difference between a genuine Flex Whip 403-520 MHz Motorola antenna used on the Jedi/Astro Saber/Visar/XTS Series radios and a comparable after-market antenna. In this case, the Motorola antenna was the silver tip antenna and the after-market antenna was from a high volume eBay reseller located Rowland Heights, CA. For several years, I have used this reseller's products as replacement parts when Motorola discontinued the respective parts and there is no other source to procure a reliable replacement part.

The VSWR for the Motorola antenna was measured with a RigExpert Antenna Analyzer at 2.3:1 @ 466 MHz and the after-market antenna measured at 2.3 MHz @ 465 MHz.

Did you check to see where they were 1:1? Every antenna is 1:1 somewhere.

I'll check the spectrum sweep parameter settings on my analyzer. Figuring the antenna center freq is about 466 I made an assumption that it sweep a wide spectrum.

 

[nokones]

The Motorola silver tip was 1.2:1 @ 516 MHz and the after-market antenna was 1.27:1 @ 532 MHz. The analyzer was set for 460 Meg as the center freq and the sweep range for +/- 200 Megs

The analyzer settings on the previous sweep was 466 Megs for the center mark and the sweep was only +/- 5 Megs thus why the aforementioned readings didn't show up.

The left antenna is a Gen 2 XPR-7xxx and XPR-3xxx antenna. Gen 1 XPR6xxx antennas use SMA and are the same/almost identical connector as the XTS/Visar/Astro Saber.

Also the Gen 2 CSA(Blue 'Smurf' radios) XPR7xxx radios also use the SMA connector as did the now discontinued 'call box' XPR7xxx radios.

No sh*t 🤦 It's a MX style bolt/stud type antenna for a Gen2.0 XPR3xxx_7xxx portable and the XTS5000 uses SMA-M chassis connector. When you screw in the antenna, the antenna element, is physically connected to ground. And if you screw it in too far, it will destroy the centre pin. If you touch the centre pin, you are grounding the centre pin to the chassis. Try attaching a Gen 1 XPR 6xxx antenna and report back.

No sh*t 🤦. It's an SMA antenna you are trying to attach to a Gen 2 XPR that uses a MX style bolt/stud connector. Try connecting that antenna to a Gen 1 XPR6xxx portable and report back...

Are you decoupling the antenna from the analyzer, and giving it a handheld sized groundplane when you are measuring VSWR?
