• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

Is there a recommended antenna for this radio other than the standard rubber duck antenna? Wondering if there might be a higher performance option available?

Nope. The stock antennas are all there is. The antenna connection point, on the XG-100P, is proprietary and not cross compatible with other antennas.

I have gotten a screw-on BNC adapter on the XG-100P once, but it was tight and I wouldn't recommend it. I don't do it anymore, but it did work.

That could possible crack the housing and then you would be SOL.

The stock antennas are also an integral part of maintaining the IP44 rating.

Those would probably perform no better than a dummy load on the XG-100P

thanks for the info gentlemen. I see Harris offers a 4.25" antenna for this radio. I assume you are giving up a lot of transmit/receive efficiencies with the small antenna?

I don’t believe that one covers vhf. They sold at least two antennas. One was a true 136-870 and the other was 380-870.

There are some aftermarket antenna relocation kits available but they are just an SMA cable and a pouch to hold the antenna, which would let you use any antenna you want, but it does compromise the ip-rating. I also have a press-on SMA adapter usually used with test equipment that fits quite nicely onto the recessed SMA on the XG100P.

The short one definitely doesn't cover VHF. It works (sort of) on RX only, but not for TX.

My XG100P came with both; I tried the short one on RX for a little while but quickly realized it was terrible, so now I only use the long one. In fact, I'm not even sure where the short one is.....

The "newer" long one also is a lot more flexible in addition to working better on VHF. New London had them awhile back.

Very much so; the new long antenna is a vast improvement. I bought one a few months back to replace my original long antenna (which was crumbling apart); I may have to order another to have it on hand just in case.

The only antenna that fits is the stock antenna. It comes in long and short. The short antenna, from experience, is horrendous with VHF. The long stock antenna is hard to find and expensive, which is why mine, used every day for my Fire Company, is covered in Gorilla Glue and gaffers tape.

New London Technology. GE-M/A-Com/Harris equipment dealer.
Thanks ... they are no where near New London. That is interesting.

Lynchburg, Virginia; former home of the GE land mobile radio division (I think L3Harris still has engineering stuff there). I don't recall offhand, but I believe NLT was originally founded as the "refurbished equipment" arm of GE Land Mobile. At the very least, whoever founded it took advantage of the fact that GE was right there.

The XG100P's antenna connector is a SMA-F connector that is recessed into the housing. Internally the SMA-F connector itself is a module, and is mounted to the mid-plate (thick aluminum plate that sits between the RF deck and the logic board). The SMA-F connects to the RF deck via coax and uses a MHF style connector to attach to the RF deck.

It is possible with appropriate SMA-F adapters to attach BNC or other SMA antennas to the radio.
