I work as electronics circuit designer for small companies do not need full time person, or companies who need temporary/part time worker. mostly RF design below 1000 MHz, PCB layout, firmware programming with C. experience with designing to pass FCC parts 15, 95, 97 devices. Rate is around $25 / hr.
Detail of Previous Projects.
YAESU FT-450D HF RADIO 100 WTS AND KENT ENGINEER STRAIGHT KEY.
I used to have 300 watts MFJ tuner, but it arched inside, when try to tune 1.8 MHz , 3.5 MHz band with 100 watts RF power with much shorter than 1/4 wave length wire.
MFJ-962D ( higher power version ) seems to work well with any length of wire at 100 watts RF level in any Band.
I also noticed wire diameter does not have to be very large, I used 22 or 24 AWG.
I think it is important to feed End Fed Wire with Current Balun, and Feed point to be close as possible as Good ground such as water pipe.
Advantage of End Fed Wire is easy hide.

CB or HF antenna mount using Attachable TOW HOOK came with car.
Suction Mount for Temporary use. Since, it does NOT have good ground, must be used with Half Wave Antenna. Half Wave design antenna, such as MFJ-1412 does not require good ground plane.
