I am thinking about purchasing Andrew/Decibel Products 'Base Commander' series antenna like is:

ASP-680, ASP-682, ASP-685 & etc.



Anybody have experience with them?

How they in comparison with RFS/Celwave, Sinclair, Procom, Kathrein & etc. base omni fiberglass antennas?

It's correct that they originally made by Antenna Specialist? I do not trust Antenna Specialist production as it is similar to cheap Chinese toys (if to speak about mobile antennas).

Any info about will be appreciated!

MotoFan,

What is your required application?

I had serious problems with the AS antennas also. Have not used any since Andrew took over them.
They have small diameter elements. <<<< This severely limits the bandwidth, frequency range, of the antenna.

I am looking for antenna for base station (operating range 162-172 MHz).

Antenna must be broadband (bandwidth => 10 MHz) and have gain 5 dBi or more.

I had serious problems with the AS antennas also. Have not used any since Andrew took over them.

Which problems and with which antennas?

They have small diameter elements.

On what is it influences, except the maximum input power? I do not have requirement for powers more than 60 watts.

I was using one in an amateur repeater application a number of years back at 340'. After about 2 years it because very harmonic in windy conditions (15 to 20 MPH) and inbound signals from the distant users were very noisy. It has since been changed to a folded dipole (DB224) with no problems since then.

I don't think it was a power issue that caused it as I was using no more than 100 watts out of the PA.

Sorry, but can you explain me what you mean more clearly?
