Re: [Repeater-Builder] Need supplier for UHF welded yagi
Hi Gran, Have a look at Comprod Communications. We have used their antennas and duplexers and are very pleased with the quality. http://www.comprodcom.com/en/antennas/base/pdf/433-70.pdf Roger VA7RS - Original Message - From: Gran Clark To: Repeater-Builder@yahoogroups.com Sent: Sunday, March 29, 2009 8:50 PM Subject: Re: [Repeater-Builder] Need supplier for UHF welded yagi Chuck I will call Sinclair.

Re: [Repeater-Builder] Need supplier for UHF welded yagi
Gran K6RIF was asking about sturdy antenna's and my suggestion was to check on the Sinclair models. As I recall the SRL307 has a bandwidth of + or - 2.5% so it would be important to know what freq. your antenna's were cut for (ie Center frequency.) 73 John VE3AMZ - Original Message - From: Gary Schafer To: Repeater-Builder@yahoogroups.com Sent: Monday, March 30, 2009 11:12 AM Subject: RE: [Repeater-Builder] Need supplier for UHF welded yagi Not sure who is looking for the yagi antenna but I have three NOS Sinclair SRL307 antennas still in the box.

Re: [Repeater-Builder] Need supplier for UHF welded yagi
It should have 20 MHz bandwidth, but, yes, the exact cut will be important. They have one for 430-450 MHz. The one I have here says SRL307*5 and lists 430-450 MHz on the sticker. The replacement model number shows the same thing in their catalog. Chuck WB2EDV - Original Message - From: John J.

Last weekend there were a number of 110 MPH gusts. The problem is wind noise. I have tightened the element hardware with some success. Spray it with water and it is quiet while tapping the boom with a small hammer. The beam is mounted on a 1 1/2 inch fiberglass pole. This is a 195 mile link and using 15 watts out of the duplexer. This has worked fairly well for fifteen years but the noise is a recurring problem. Some thoughts using conductive epoxy, came to mind but also I was looking for a supplier of a welded maybe 9 element yagi that might work. We need a yagi to give co channel protection to the North (beam headed East). Gran K6RIF

Tessco/Larson sells this one: http://www.tessco.com/products/displayProductInfo.do?sku=57015eventPage=1 Scala is a favorite among broadcasters, and sells this one with a radome: http://www.kathrein-scala.com/catalog/RA5-400B.pdf BTW, Google is amazing. I plugged in welded yagi and at the top of the rankings was your original post.
