Every ClearBoost that has been ordered has been shipped, except I think one which I do not have a survey for. The last units shipped out at the start of this week, with the vast majority going out the prior two weeks. We were testing, assembling, packing and shipping them as fast as we could. Rob handled all the assembly and shipping which was fantastic as it gave me time to individually tune each unit to ensure the optimal response was over video channels. In total we shipped over 550 units in around 2 weeks.
Last week we looked at the stock Lawmate 1.2GHz Transmitter antennas which was very good for one channel, not so great for pretty much anything else. This week we're going to take a look at an option from DragonLink. They call this a video Transmitter antenna, however there is no reason why it cannot be used on a receiver as well. These are the same style as the 433MHz receiver antennas.
If we are going to be reviewing antennas from a electrical standpoint, we need a reference antenna, so I'm going to review the stock ImmersionRC dipole antenna. Hopefully we'll get to the BOSCAM/other chinese stock antennas soon. If you are looking at an antenna upgrade, this might just be what you are upgrading from if you use FatShark or ImmersionRC equipment.
With the testing equipment we have for quality assurance on our ClearBoost, we're able to test the reflection parameters of antennas in any frequency up to 6GHz. I'm going to start the testing with my favourite long range antenna for 5.8GHz, the Circular Wireless HELIAXIAL58. As a note, this antenna is several years old, but has always been kept in its retail box when not in use.
