Hi, I’m Alex. Here is my software for everyone. It is completely free. Enjoy!

**EFFECTIVE ISOTROPIC RADIATED POWER CALCULATOR ERPC v.1.02**

Very easy to use. Enter RF power, known antenna gain and approximate total cable losses. Click on “Calculate”. The ERP and EIRP results would be on right side. The difference is just reference to isotropic antenna or dipole. Also you’ll be able to convert dBd to dBi.

============================================================================================================

**BIAS TEE CALCULATOR BTC v.1.02**

The Bias Tee calculator helps to calculate the values for a typical bias tee circuit (capacitance C and inductance L). You have to put input and output impedance, frequency and impedance ratio (usually value of 100). Right now the XL and XC calculates based on fixed impedance ratio but in next version they will be variable depend on different brands of capacitors and inductors.

**ENGINEERING CALCULATOR EC v.1.06**

If you are designer and work with power amplifiers you will like this program.

There is

– Power Amplifier Calculator

– RC Time Constant Calculator

– Attenuator Calculator

– Watts to dBm and dBm to Watts Calculator

All test data can be save as TXT file.

**EASY CONVERSION CALCULATOR ECC v.1.0**

A simple conversion calculator for everyday use US to Metric and Metric to US.

**FREE SPACE LOSS CALCULATOR FSL v.1.0**

For your convenient use – FSL Calculator.

**ANTENNA STACKING CALCULATOR ASC v.1.05**

You may find it useful. It calculates the stacking distance V and H in 4 antenna stack array.

send me the driver for sound interface mod. sid-01a yaesu trx.

tnx i1oje

can you help me calculate the vertical stacking distance for 3 of the same type antenna (telewave ANT500Y10-wr horisontal type). my frequency is 503mhz. i want to maximize on my forward gain

No problem. Done.

Hello, is your antenna stacking calculator suitable for only two antennas vertical stacking and how? Thank you in advance
