I have started making a fiberglass polyester resin Radome for my L-Band Antenna Kit.
Fiberglass apparently has good attenuation for L-Band signal but I do not know exactly how good it is.
I have rounded all corners so that I hopefully will eliminate distorting the signal.
The offsets for the time being are at the front and hold off the front face of the L-Band antenna. This means a small part of the offset is also blocking the signal.
I have allowed 2cm above the antenna front face so as to avoid / lower the interference Syed was talking about from having the Lantern plastic to close to the antenna.
I will not paint the Radome for a few weeks to get a feel for the attenuation with plain fiberglass. I plan to paint it white.
The electronics will sit on a fiberglass plate under the antenna. I thought about lining the plate with foil to stop the E4000 and the LNA interfering with the antenna but as the LNA and E4000 are in metal boxes I am happy to try it without foil.
One problem is the e4000 and the LNA come with direct connection so there is not a lot of room to fit it in. I will order a 90 degree SMA elbow but for the time being I will use a small sma pigtail to help fit it in.
I do not want to put any force or bending on the thin coax.
