The shack is coming along nicely. Installed single point grounding system of all equipment to grounding rod 8 feet deep outside. No ground loops here. .

Видео снято мной на хамфесте в городе Дейтон.
Занимаюсь организацией поставок средств связи из Китая.

The 4x4 Bug Out Vehicle (BOV) solar panels installed on the Expedition. Easy on/off designed unistrut rail system. Very low profile. In full sun it's generating over a 150 watts, 40.2 Volts, 7 amps into a 10 amp PMW solar controller that converts to 12 volts system. Both panels are wired in series configuration for maximum voltage. A DC to AC Invertor is connected to a single 75aH battery which offers 120 volt functionality. Such as additional HT radio charging stations or adding a local WIFI router for possible networking of multiple users at the IC/Command post. This system will allow me to be fully functional using my HF and VHF Radios. Inside the Vehicle uses LED lighting for night time. The system also has three 5.3 volt USB ports for charging phones and any USB device.
.
This is not only for Bug Out purposes, but to be used for EMCOMM (Emergency Communications), IC incident command / command post. Best locations to park this vehicle will always be at highest elevation near an incident, especially in mountainous terrain during search rescue operations were radio communications can be difficult.
.
In addition to power, upon deployment, a portable 5/8ths wave ground plane antenna on a tripod for VHF radio is raised. HF antennas are wire and simply put up in trees.
The expedition has 1/4 wave and 5/8ths wave 2 meter antennas installed in addition.

See previous pic. This is NOT your typical 1/4 wl ground plane. It has a very low angle of radiation, about 8 degrees. Since this very low angle of radiation exists, why not adapt it for "base station use" for regular 2 meter land based communications. This home brewed antenna is modified to get our signal lower to the ground where it is needed most instead of heating up lots of air at a higher angles!
.
Design:
This is a high-efficiency "gain" antenna. It is not mounted permanently: I use it for EMCOMM on a tripod extended 15 feet high.
The antenna is an atypical vertical: instead of the common 1/4 wl vertical monopole or 1/4 wl ground plane with 1/4 wl radials, this design employs a 3/8 wl vertical section and short radials to complete the "ground plane." Effectively, an off-center-fed vertical dipole that does not rely on the earth to complete the bottom half of the antenna. This is an important point. The fact the antenna has a fully contained lower half, i.e., the ground plane, makes it very efficient.

This is your last chance. After this, there is no turning back. You take the blue pill—the story ends, you wake up in your bed and believe whatever you want to believe. You take the redpill—you stay in Wonderland, and I show you how deep the rabbit hole goes. Remember: all I'm offering is the truth. Nothing more.
