• 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.

Im sure I have asked this before What is the advantage of the NAF5039 dipole vs NAF5037. I have both antennas I really do not see a difference in reception. Only advantage I see is the dipole doesn't bend at all. The diploe seems to be more of a nuisance than any thing.

The elevated feed design came out with the STX series back a long...long time ago. The idea was to get the actual antenna part up and above your head when holding the ht while using it. Years ago I had a STX with the dipole and normal antennas, I also saw no difference between the two.

The NAF5039 on the old Type II systems had its advantages in fringe areas and in thick walled buildings. We noted a marginal increase in clear (analog) coverage using the Dipole antenna. I'm not sure how well they would perform today in a Simulcast Phase I or Phase II P25 system with the multi tower (saturated coverage) approach. As a side note, if you cut the skirt off the bottom and attach it to a Unication G4/G5 the coverage is phenomenal. Just a pro tip. :cool:

I see lol the antenna doesn't fit on the xts 2500 as well as the xts5000. I was just curious seems like i got a collection of those dipole antennas around. They do work just thinking electrically it work better.

Weird, I do have one on my XTS5000. Fits perfect with the skirt. Good Luck! :)

That was true on our legacy Smartnet II simulcast system. All the STX821s and MTS2000s were ordered with them. When I first got on with my agency, I had to do an inventory of all subscribers. I found boxes of the 5039s. Sadly, as most Motorola antennas seem to suffer, most were dry rotted despite being kept in cool (65 degree air conditioned server room in a dark cabinet) place.

I first put one on a few 5000s while we were doing testing of our new Astro 25 system and noticed no difference in RSSI or BER between that and the 5/8 wave whips that came with the 5K.

I tried the naf5042 1/4 today it makes the signal on my 2500 go way down. I wander if the antenna for the apx radios that are smaller would work better?
