• 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.

Larsen vs. Laird Tri-band

Not those specific models.

But I have some of each brand, and I've been happy with both of the brands. Both have been durable and stood up to a lot of abuse.
My personal favorite is the Larsen brand, though. I have some 30 year old Larsen antennas that have outlasted the vehicles they were installed on. The bases are pretty durable and well designed.

I own both using Tri-Bands with third party 3.5" NMO mounts on Nissan's Maxima vehicles. Paired with Uniden UBC126AT and/or TRX-1 scanner when traveling. I found no noticeable difference far as performance goes. Happy with both despite using different band plan.
Mainly 75.xxx, Air, 140.xxx, 420.xxx, 485.xxx MHz. Reception is very good on all frequencies considering used in moving vehicle.
Thank you Mr mmckenna for your recommendation few years ago.

I've been using the Larsen 150/450/800 tri-band black unity gain antenna now for many years.... Love the low profile....... I pick up CHP Low band all the way up to the 800.... P25...... all crystal clear ..... A old scanner dealer in the SF Bay area told me about it .....he said you will not find anything better (I was stubborn and tried others) But he was right and I was wrong........Note.... the specs dont show low band... but it does very well on it

I have used both and have chosen the Larson newer tri-band with the spring as better reception. I've noticed reception is the same as the older Tri band Larson but I too like the new mount with the larger seal.
