One can always dream.  Even if you can't duplicate N1BUG's antenna, you can find a variety of designs online that could fit into your small urban lot or housing situation. With propagation being what it is these days, you may want to discover what 160 meters can offer.  At the very least, 160 meters makes an excellent "rag chew" spot for local and regional contacts.

In this video from Julian (OH8STN), we see how an attic-mounted magnetic loop solved a major antenna issue for Julian's friend and former colleague in Ukraine. The antenna installation consists of the popular Chameleon F-Loop with the RTRR rotator tuner--all remotely controlled from the ham shack.  Hopefully, this antenna will be the answer to some of your antenna problems.

9 Brilliant Ideas To Make Your Own Dummy Load. Post 1714.

9 Brilliant Ideas To Make Your Own Dummy Load https://www.dxzone.com/9-ideas-to-make-your-own-dummy-load/ Accessed on 17 December 2018, 2253 UTC, Post 1714. Comment: A "dummy load" should be required equipment for any ham shack or electrical experimenter's bench.  Simply put, a "dummy load" is an off-air device used to adjust and tune a transceiver.  A "dummy load" is a simulated antenna that permits test transmissions with out radiating rf energy beyond the device. Here are several "dummy load" projects from our friends at the DX Zone: A 100 watt dummy load. A 5400 watt dummy load. A 50 ohm dummy load. N5ESE QRP dummy load. QRP Power Meter and dummy load. An oil-filled dummy load. How to build a 130 watt dummy load (excellent video tutorial). Most of these projects can be built using locally available materials.  Any one of these dummy loads will make for an excellent weekend project.  Have fun and reduce RFI at the same
