## Questions & Answers

**Q: Is the bidirectional?**
A: No, it's Tx (transmission) only

**Q: Is this a bidirectional ?**
A: No! Bi directional is very expensive

**Q: What is the minimum input wattage?**
A: I used this with a 100mW RFM69HCW module and got just under 10 dB gain at close range.

## Customer Reviews

### ⭐ Bad product
*by G***3 on March 24, 2025*

This Amp had damaged connnectors and it had a very high unusable SWR reading. The only reason it did t get returned is because I forgot to do it in time

### ⭐⭐⭐ Came in under specs using recommed voltage.
*by M***Y on January 6, 2024*

Source\Measurement: Rigol DSA815, all options.Input: 0dbmVoltage: 5.0Load: 50 ohm. Florida RF Labs 32-1026; 0-4ghz. 150W Max. 1.35VSWR worst case.Sweep: “0” to 1.5ghz, normalized.Use the attached pic of the graph and calculate your dbm for the target freq you have (wattage for those who don't know, but if you don't know that don't play with RF) . It did outperform in early portion of the bands. Overall, really impressed with performance. Did not go up in smoke during the bench mark!They did actually remove the prongs on the bottom side of the SMA so it lays flat on the heatsink (most don't). I did modify and put a thermal pad and left the legs on. The thermal pad is thicker than the legs and squished down.73,KC9oXP

### ⭐⭐⭐⭐⭐ Good so far
*by Z***L on August 31, 2022*

This seems to be a transmission booster. It doesn't allow bi-directional communication, but the antenna line from my radio module (RFM69HCW) is leaky enough to allow some reception with this booster connected.The increase in signal strength seems good so far. I get an extra 20dB at close range. I haven't tested the maximum range yet. I seem to get the best gain increase at short range with GFSK modulation. OOK modulation yielded around 10dB of signal increase.The heatsink requires some forced airflow as it gets too hot for my liking.All in all it's a decent signal booster at an unbeatable price.
