It is way too long. I have one side of it draped over the roof, and only 20 ft high at the apex. It&#8217;s too low and too long, performs relatively poorly, and is a very noisy RX antenna. Sure, I made plenty of DX contacts using it, but I have to wonder what it&#8217;s been missing buried in the noise.<\/p>\n\n\n\n<p>There were <a rel=\"noreferrer noopener\" aria-label=\"5 online reviews (opens in a new tab)\" href=\"https:\/\/www.eham.net\/reviews\/detail\/8021\" target=\"_blank\">5 online reviews<\/a> of the older model TD-90, and 4 of them praised its low noise RX, which immediately caught my attention. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Max Gain Systems: 38 ft Push-Up Mast<\/h2>\n\n\n\n<p>I bought <a href=\"https:\/\/mgs4u.com\/fiberglass-push-up-masts\/#masts\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"one of these push-up masts (opens in a new tab)\">one of these push-up masts<\/a> and had it up for 12 years in the Southern California sun with no problems whatsoever.

I ran a few &#8216;triangle&#8217; calculations and it looks like a possible fit. The ends will be East and West (broadside North and South) as I have no other options. This is the same general direction as the existing dipole.<\/p>\n\n\n\n<p>A bit more research is required, but I&#8217;m leaning heavily in this direction tonight!<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><a href=\"http:\/\/k6hr.com\">Back To The Front<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Under Consideration: Tennadyne TD-SS90 Since installing the Flex 6700 and 6500 transceivers I&#8217;ve come to appreciate the amazing low noise RX these two radios provide.
