I have an APX 8500 base station that needs a 700/800 antenna. This is the only band currently in use. Can anyone recommend a simple indoor antenna setup to try as mouting.an antenna outdoors will be problamatic? Singal strength inside rhe building is decent.

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 the radio on a trunked system? How often will you be transmitting? Are you able to reduce the transmit power?
Trucked system and only transmitting a couple times a week. I will have to look into the transmit power options.

At work, in this sorts of applications, I just have them use a standard 800MHz 1/4 wave whip on a mag mount. That would get stuck on a file cabinet or window sill. Keep the power low if you do programming. Or, just make sure it's spaced away from the user.

I used to deliver cars to the HUGE car rental return building across from the Miami Airport. Basically a 4 story parking garage, in the office they had a radio on the counter with a magnetic antenna sitting on the radio. I had to laugh.

It drives the radio guy inside me nuts, but it works.
I -really- want to do an external antenna, but the cost/effort is beyond what they want to spend. Usually these installs are places where a portable works fine, but battery charging/replacement becomes more costly than just doing a mobile with a power supply.

At least it works, & the radio operator’s face isn’t 6 inches from the antenna. At the Hertz garage, the coax was tightly coiled with the magnetic antenna on the radio which was sitting on the PS, & the radio operator‘s face less than a foot away. And this office was deep in the bowels of the parking structure, but by a window facing towards a concrete wall.

This gave me flashbacks to a plant control room radio I once used. Kenwood TK-980 with a magnetic car phone antenna stuck to a giant nut that probably came off a jaw crusher. The antenna was set on the exterior windowsill a few feet from the motor control panel. It did in fact work.It drives the radio guy inside me nuts, but it works.

If I can find four rotating coaxial joints I might move all my car antennas to the hub caps and drive that way.It drives the radio guy inside me nuts, but it works.

The Ben Hur mount? It would be interesting to see at what speed the whip goes straight.

Laugh all you want.. It's common to do that We call it a control station and its set to 5 w . Businesses and airports do it as to not have to use a handheld radio and get lost. stolen or battery not charged.
Relocated an 800Mhz control station for a medical lab company courier service one time. They had an 800Mhz mobile antenna on a mag mount affixed to a STOP sign above the drop ceiling. Apparently it worked for them.....
Filing cabinets make a great mag mount holder.
