Big hello from the south edge of Morro Bay onthe CA central coast - often foggy, pretty much always mild temperatures. I am a semi-retired I & C (instrument and controls) engineer. Graduated from Cal Poly Univ. in the mid-70's and nowpart-time lecturer inits EE department. Other interests are racing pigeons and fishing.
Main rig is anApache ANAN-100bon HF, Baofeng hand-held for VHF/UHF, SDR usb donglefor wide-band rx. The multi-loop antennain the picture is used for Rxonly (0.5 - 55MHz). Its preamp (LA1AQ AAA-1) allowsremote switchingto two upper loops (in cross-parallel), the bottom loop,allloopstogether or adipole of thetop whip and shorted bottom loop.
Currently using a(RG-6) coax spiral (60ft arms) antenna laid out on my roof forTx on bandsnot covered bymy MFJtuned loop(40m -15m).TheMFJis mounted vertically on a rotatoronly 2ft above my roof and still gets out pretty good. BW is about 20kHz and SWR is easy to setbelow 1.5.Except on 40m, where they are about equal, the MFJ gets substantially more rangeat a given Txpower than the spiral. MFJ's Rx ismuch noisier than the mult-loop. I shortened the MFJ's feed loop by about 1/4in from what it was as receivedand itimproved matching. Looking at adding some length to thespiral and some small directionals below theMFJfor 12m, 10m,6m & up.
Antenna/s more than a couple feet above roof impractical, but I do have a great view of Morro Bay from the shack. The coaxspiral (Morro Rock in background) and MFJ tuned loop areright above my station and shown just below the view.
