I'll second that suggestion. Electrical tape and duct tape are absolutely useless to seal antenna and coax connections. The self-fusing silicone tape is great and will keeps connections clean and dry for years. One commonly found brand is Nashua Stretch & Seal. You can usually find it at your local orange big box home improvement store.
