gain

Hi, I'm relocating some of the antennas that I have and I came across the Gainmaster that I have on a 6m aluminium pole (on a 2m high extension roof) and I plugged it to my meter and it shows as having between 15 to 25 omhs across the 11m band. The coax used is 3m long RG213 cable and the...

Suppose that I'm installing an omnidirectional antenna for both transmission & reception purpose at the elevation of ≈100ft. If I want to effectively communicate with a few targets all at the elevation of ≈0ft and horizontally ≈5100ft from the antenna, what's the maximum acceptable gain for this...

I've looked around on the web and read previous threads where the MTS2000 experiences low transmit audio on occasion. Is there anything within the CPS that can fix the gain on the microphone on the HT itself? I've checked the CPS and couldn't seem to find anything. I see AGC but after...

What is the dB gain (in dBd) for the OEM antenna that comes with the BC92XLT? I am considering an upgrade but I want to know how much of an improvement I am making to determine if it's worth the cost.

I own a Uniden Bearcat BCD396XT MOBILE scanner and only listen to Fire/EMS and police frequencies, which are from 151-155 MHz VHF, and occasionally a 453 MHz channel. I am curious what antenna to get for my portable scanner to pick up one of the dispatch centers around 20 mi away. Also, what...

Hello all: Looking for some technical and experienced insight. This is a public safety system that operates at 154.1800. We are having to replace the antenna and are 340W ERP. The repeater currently has a DB224 but I am pushing for a DB228 to help receiving the handhelds. Adding the DB224 to...

Hello, I have had my license for going on 2 years but haven't done much with it. Well I am now over the age of 18 and I have a good steady income coming in so I was wondering about buying a new HT. I owned a Yaesu VX-7R a few years ago. I plan on buying another one. I was wondering if this is a...
